+# Packaging Debug and Release #
+
+By default CMake is model is that a build directory only contains a single
+configuration, be it Debug, Release, MinSizeRel, or RelWithDebInfo.
+
+But it is possible to setup CPack to bundle multiple build directories at the same
+time to build a package that contains multiple configurations of the same project.
+
+First we need to ahead and construct a directory called 'multi_config' this
+will contain all the builds that we want to package together.
+
+Second create a 'debug' and 'release' directory underneath 'multi_config'. At
+the end you should have a layout that looks like:
+
+─ multi_config
+    ├── debug
+    └── release
+
+Now we need to setup debug and release builds, which would roughly entail
+the following:
+
+  cd debug
+  cmake -DCMAKE_BUILD_TYPE=Debug ../../MultiPackage/
+  cmake --build .
+  cd ../release
+  cmake -DCMAKE_BUILD_TYPE=Release ../../MultiPackage/
+  cmake --build .
+  cd ..
+
+
+Now that both the debug and release builds are complete we can now use
+the custom MultiCPackConfig to package both builds into a single release.
+
+  cpack --config ../../MultiPackage/MultiCPackConfig.cmake

+# Adding a Version Number and Configured Header File #
+
+The first feature we will add is to provide our executable and project with a
+version number. While we could do this exclusively in the source code, using
+CMakeLists provides more flexibility.
+
+To add a version number we modify the CMakeLists file as follows:
+
+  cmake_minimum_required(VERSION 3.3)
+  project(Tutorial)
+
+  # the version number.
+  set(Tutorial_VERSION_MAJOR 1)
+  set(Tutorial_VERSION_MINOR 0)
+
+  # configure a header file to pass some of the CMake settings
+  # to the source code
+  configure_file(
+    "${PROJECT_SOURCE_DIR}/TutorialConfig.h.in"
+    "${PROJECT_BINARY_DIR}/TutorialConfig.h"
+    )
+
+  # add the executable
+  add_executable(Tutorial tutorial.cxx)
+
+  # add the binary tree to the search path for include files
+  # so that we will find TutorialConfig.h
+  target_include_directories(Tutorial PUBLIC
+                             "${PROJECT_BINARY_DIR}"
+                             )
+
+
+We then create a TutorialConfig.h.in file in the source tree with the
+following contents:
+
+  // the configured options and settings for Tutorial
+  #define Tutorial_VERSION_MAJOR @Tutorial_VERSION_MAJOR@
+  #define Tutorial_VERSION_MINOR @Tutorial_VERSION_MINOR@
+
+When CMake configures this header file the values for @Tutorial_VERSION_MAJOR@
+and @Tutorial_VERSION_MINOR@ will be replaced by the values from the CMakeLists
+file. Next we modify tutorial.cxx to include the configured header file and to
+make use of the version numbers. The resulting source code is listed below.
+
+  // A simple program that computes the square root of a number
+  #include <cmath>
+  #include <iostream>
+  #include <string>
+  #include <sstream>
+
+  #include "TutorialConfig.h"
+
+  int main (int argc, char *argv[])
+  {
+    if (argc < 2)
+      {
+      std::cout << argv[0] << " Version "
+                << Tutorial_VERSION_MAJOR << "." << Tutorial_VERSION_MINOR
+                << std::endl;
+      std::cout << "Usage: " << argv[0] << " number" << std::endl;
+      return 1;
+      }
+
+    double inputValue = atof(argv[1]);
+
+    double outputValue = sqrt(inputValue);
+    std::cout << "The square root of "
+              << inputValue << " is " << outputValue << std::endl;
+    return 0;
+  }
+
+# Adding C++11 support #
+
+Let's add some C++11 features to our project. We will need to explicitly state
+in the CMake code that it should use the correct flags. The easiest way to
+enable C++11 support for CMake is by using the CMAKE_CXX_STANDARD
+and CMAKE_CXX_STANDARD_REQUIRED variables.
+
+First, replace `atof` with `std::stod` in tutorial.cxx.
+
+Then, add the CMAKE_CXX_STANDARD and CMAKE_CXX_STANDARD_REQUIRED variables to
+the CMakeLists file. The STANADARD value should be set to 11, and REQUIRED
+should be set to True.
+
+
+# Build and Test #
+
+Run cmake or cmake-gui to configure the project and then build it with your
+chosen build tool
+
+cd to the directory where Tutorial was built (likely the make directory or
+a Debug or Release build configuration subdirectory) and run these commands:
+
+  Tutorial 4294967296
+  Tutorial 10
+  Tutorial

+# Adding Generator Expressions #
+
+Generator expressions are evaluated during build system generation to produce
+information specific to each build configuration.
+
+Generator expressions are allowed in the context of many target properties, such
+as LINK_LIBRARIES, INCLUDE_DIRECTORIES, COMPILE_DEFINITIONS and others. They may
+also be used when using commands to populate those properties, such as
+target_link_libraries(), target_include_directories(),
+target_compile_definitions() and others.
+
+Generator expressions may to used to enable conditional linking, conditional
+definitions used when compiling, and conditional include directories and more.
+The conditions may be based on the build configuration, target properties,
+platform information or any other queryable information.
+
+There are different types of generator expressions including Logical,
+Informational, and Output expressions.
+
+Logical expressions are used to create conditional output. The basic expressions
+are the 0 and 1 expressions. A "$<0:...>" results in the empty string, and
+"$<1:...>" results in the content of "...".  They can also be nested.
+For example:
+
+  if(HAVE_LOG AND HAVE_EXP)
+    target_compile_definitions(SqrtLibrary
+                               PRIVATE "HAVE_LOG" "HAVE_EXP")
+  endif()
+
+Can be rewritten with generator expressions:
+
+  target_compile_definitions(SqrtLibrary PRIVATE
+                             "$<$<BOOL:${HAVE_LOG}>:HAVE_LOG>"
+                             "$<$<BOOL:${HAVE_EXP}>:HAVE_EXP>"
+                            )
+
+Note that "${HAVE_LOG}" is evaluated at CMake configure time while
+"$<$<BOOL:${HAVE_LOG}>:HAVE_LOG>" is evaluated at build system generation time.

+# Adding Export Configuration #
+
+During Step 4 of the tutorial we added the ability for CMake to install the
+library and headers of the project. During Step 7 we added the ability
+to package up this information so it could be distributed to other people.
+
+The next step is to add the necessary information so that other CMake projects
+can use our project, be it from a build directory, a local install or when
+packaged.
+
+The first step is to update our install(TARGETS) commands to not only specify
+a DESTINATION but also an EXPORT. The EXPORT keyword generates and installs a
+CMake file containing code to import all targets listed in the install command
+from the installation tree. So let's go ahead and explicitly EXPORT the
+MathFunctions library by updating the install command in
+MathFunctions/CMakeLists.txt to look like:
+
+  install(TARGETS MathFunctions DESTINATION lib EXPORT MathFunctionsTargets)
+
+Now that we have MathFunctions being exported, we also need to explicitly install
+the generated MathFunctionsTargets.cmake file. This is done by adding
+the following to the bottom of the top-level CMakeLists.txt:
+
+  # install the configuration targets
+  install(EXPORT MathFunctionsTargets
+    FILE MathFunctionsTargets.cmake
+    DESTINATION lib/cmake/MathFunctions
+  )
+
+At this point you should try and run CMake. If everything is setup properly
+you will see that CMake will generate an error that looks like:
+
+  Target "MathFunctions" INTERFACE_INCLUDE_DIRECTORIES property contains
+  path:
+
+    "/Users/robert/Documents/CMakeClass/Tutorial/Step11/MathFunctions"
+
+  which is prefixed in the source directory.
+
+What CMake is trying to say is that during generating the export information
+it will export a path that is intrinsically tied to the current machine and
+will not be valid on other machines. The solution to this is to update the
+MathFunctions target_include_directories to understand that it needs different
+INTERFACE locations when being used from within the build directory and from an
+install / package. This means converting the target_include_directories
+call for MathFunctions to look like:
+
+  target_include_directories(MathFunctions
+                             INTERFACE
+                              $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}>
+                              $<INSTALL_INTERFACE:include>
+                             )
+
+Once this has been updated, we can re-run CMake and see verify that it doesn't
+warn anymore.
+
+At this point, we have CMake properly packaging the target information that is
+required but we will still need to generate a MathFunctionsConfig.cmake, so
+that the CMake find_package command can find our project. So let's go ahead and
+add a new file to the top-level of the project called Config.cmake.in with the
+following contents:
+
+  @PACKAGE_INIT@
+
+  include ( "${CMAKE_CURRENT_LIST_DIR}/MathFunctionsTargets.cmake" )
+
+Then, to properly configure and install that file, add the following to the
+bottom of the top-level CMakeLists:
+
+  include(CMakePackageConfigHelpers)
+  # generate the config file that is includes the exports
+  configure_package_config_file(${CMAKE_CURRENT_SOURCE_DIR}/Config.cmake.in
+    "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsConfig.cmake"
+    INSTALL_DESTINATION "lib/cmake/example"
+    NO_SET_AND_CHECK_MACRO
+    NO_CHECK_REQUIRED_COMPONENTS_MACRO
+    )
+  # generate the version file for the config file
+  write_basic_package_version_file(
+    "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsConfigVersion.cmake"
+    VERSION "${Tutorial_VERSION_MAJOR}.${Tutorial_VERSION_MINOR}"
+    COMPATIBILITY AnyNewerVersion
+  )
+
+  # install the configuration file
+  install(FILES
+    ${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsConfig.cmake
+    DESTINATION lib/cmake/MathFunctions
+    )
+
+At this point, we have generated a relocatable CMake Configuration for our project
+that can be used after the project has been installed or packaged. If we want
+our project to also be used from a build directory we only have to add
+the following to the bottom of the top level CMakeLists:
+
+  # generate the export targets for the build tree
+  # needs to be after the install(TARGETS ) command
+  export(EXPORT MathFunctionsTargets
+    FILE "${CMAKE_CURRENT_BINARY_DIR}/MathFunctionsTargets.cmake"
+  )
+
+With this export call we now generate a Targets.cmake, allowing the configured
+MathFunctionsConfig.cmake in the build directory to be used by other projects,
+without needing it to be installed.

+# Adding a Library #
+
+Now we will add a library to our project. This library will contain our own
+implementation for computing the square root of a number. The executable can
+then use this library instead of the standard square root function provided by
+the compiler.
+
+For this tutorial we will put the library into a subdirectory
+called MathFunctions. It will have the following one line CMakeLists file:
+
+  add_library(MathFunctions mysqrt.cxx)
+
+The source file mysqrt.cxx has one function called mysqrt that provides similar
+functionality to the compiler’s sqrt function. To make use of the new library
+we add an add_subdirectory call in the top-level CMakeLists file so that the
+library will get built. We add the new library to the executable, and add the
+MathFunctions as an include directory so that mqsqrt.h header file can be
+found. The last few lines of the top-level CMakeLists file now look like:
+
+
+  add_subdirectory(MathFunctions)
+
+  #add the executable
+  add_executable(Tutorial tutorial.cxx)
+
+  target_link_libraries(Tutorial ${EXTRA_LIBS})
+
+
+Now let us make the MathFunctions library optional. While for the tutorial
+there really isn’t any need to do so, but with larger projects this is a common
+occurrence. The first step is to add an option to the top-level CMakeLists file.
+
+  option (USE_MYMATH
+          "Use tutorial provided math implementation" ON)
+
+This will show up in CMake GUI and ccmake with a default value of ON that can
+be changed by the user. This setting will be stored so that the user does not
+need to set the value each time they run CMake on this build directory.
+
+The next change is to make building and linking the MathFunctions library
+conditional. To do this we change the top-level CMakeLists file to look like
+the following:
+
+  cmake_minimum_required(VERSION 3.3)
+  project(Tutorial)
+
+  set(CMAKE_CXX_STANDARD 11)
+  set(CMAKE_CXX_STANDARD_REQUIRED True)
+
+  # the version number.
+  set(Tutorial_VERSION_MAJOR 1)
+  set(Tutorial_VERSION_MINOR 0)
+
+  # configure a header file to pass some of the CMake settings
+  # to the source code
+  configure_file(
+    "${PROJECT_SOURCE_DIR}/TutorialConfig.h.in"
+    "${PROJECT_BINARY_DIR}/TutorialConfig.h"
+    )
+
+  # should we use our own math functions
+  option(USE_MYMATH "Use tutorial provided math implementation" ON)
+
+  # add the MathFunctions library?
+  if(USE_MYMATH)
+    add_subdirectory(MathFunctions)
+    list(APPEND EXTRA_LIBS MathFunctions)
+    list(APPEND EXTRA_INCLUDES "${PROJECT_SOURCE_DIR}/MathFunctions")
+  endif(USE_MYMATH)
+
+  # add the executable
+  add_executable(Tutorial tutorial.cxx)
+
+  target_link_libraries(Tutorial ${EXTRA_LIBS})
+
+  # add the binary tree to the search path for include files
+  # so that we will find TutorialConfig.h
+  target_include_directories(Tutorial PUBLIC
+                             "${PROJECT_BINARY_DIR}"
+                             ${EXTRA_INCLUDES}
+                             )
+
+Note the use of the variables EXTRA_LIBS, and EXTRA_INCLUDES to collect
+up any optional libraries to later be linked into the executable. This is a
+classic approach when dealing with many optional components, we will cover the
+modern approach in the next step. For now the corresponding changes to the
+source code are fairly straightforward and leave us with:
+
+  #ifdef USE_MYMATH
+    double outputValue = mysqrt(inputValue);
+  #else
+    double outputValue = sqrt(inputValue);
+  #endif
+
+Since the source code now requires USE_MYMATH we can add it to the
+TutorialConfig.h.in. Simply add the following line:
+  #cmakedefine USE_MYMATH
+
+Run cmake or cmake-gui to configure the project and then build it with your
+chosen build tool and then run the built Tutorial executable.
+
+Which function gives better results, Step1’s sqrt or Step2’s mysqrt?

+# Adding Usage Requirements for Library #
+
+Usage requirements allow for far better control over a library / executable's
+link and include line. While also giving more control over the transitive
+property of targets inside CMake. The primary commands that leverage usage
+requirements are:
+
+  - target_compile_definitions
+  - target_compile_options
+  - target_include_directories
+  - target_link_libraries
+
+First up is MathFunctions. We first state that anybody linking to MathFunctions
+needs to include the current source directory, while MathFunctions itself
+doesn't. So this can become an INTERFACE usage requirement.
+
+Remember INTERFACE means things that consumers require but the producer doesn't.
+
+  target_include_directories(MathFunctions
+            INTERFACE ${CMAKE_CURRENT_SOURCE_DIR})
+
+Now that we've specified usage requirements for MathFunctions we can safely remove
+our uses of the EXTRA_INCLUDES variable.
+
+Run cmake or cmake-gui to configure the project and then build it with your
+chosen build tool.

+
+Now we can start adding testing support and install rules to our project.
+
+The install rules are fairly simple; for MathFunctions we install the library
+and header file, for the application we install the executable and configured
+header.
+
+So to MathFunctions/CMakeLists.txt we add:
+
+  install (TARGETS MathFunctions DESTINATION bin)
+  install (FILES MathFunctions.h DESTINATION include)
+
+And the to top-level CMakeLists.txt we add:
+
+  install(TARGETS Tutorial DESTINATION bin)
+  install(FILES "${PROJECT_BINARY_DIR}/TutorialConfig.h"
+          DESTINATION include
+          )
+
+That is all that is needed to create a basic local install of the tutorial.
+
+Run cmake or cmake-gui to configure the project and then build it with your
+chosen build tool. Then build the “install” target by typing 'make install'
+from the command line or build the INSTALL target from an IDE. This will
+install the appropriate header files, libraries, and executables.
+
+Verify that the installed Tutorial runs. Note: The CMake variable
+CMAKE_INSTALL_PREFIX is used to determine the root of where the files will
+be installed.
+
+Next let's test our application. Adding testing is an easy process. At the
+end of the top-level CMakeLists file we can add a number of basic tests to
+verify that the application is working correctly.
+
+  # enable testing
+  enable_testing()
+
+  # does the application run
+  add_test(NAME Runs COMMAND Tutorial 25)
+
+  # does the usage message work?
+  add_test(NAME Usage COMMAND Tutorial)
+  set_tests_properties(Usage
+    PROPERTIES PASS_REGULAR_EXPRESSION "Usage:.*number"
+    )
+
+  # define a function to simplify adding tests
+  function(do_test target arg result)
+    add_test(NAME Comp${arg} COMMAND ${target} ${arg})
+    set_tests_properties(Comp${arg}
+      PROPERTIES PASS_REGULAR_EXPRESSION ${result}
+      )
+  endfunction(do_test)
+
+  # do a bunch of result based tests
+  do_test(Tutorial 25 "25 is 5")
+  do_test(Tutorial -25 "-25 is [-nan|nan|0]")
+  do_test(Tutorial 0.0001 "0.0001 is 0.01")
+
+The first test simply verifies that the application runs, does not segfault or
+otherwise crash, and has a zero return value. This is the basic form of a CTest
+test.
+
+The Usage test uses a regular expression to verify that the usage message
+is printed when an incorrect number of arguments are provided.
+
+Lastly, we have a function called do_test that simplifies running the
+application and verifying that the computed square root is correct for given
+input.
+
+To run tests, cd to the binary directory and run “ctest -N” and “ctest -VV”.

+# Adding System Introspection #
+
+Let us consider adding some code to our project that depends on features the
+target platform may not have. For this example, we will add some code that
+depends on whether or not the target platform has the log and exp functions. Of
+course almost every platform has these functions but for this tutorial assume
+that they are not common.
+
+If the platform has log and exp then we will use them to compute the square
+root in the mysqrt function. We first test for the availability of these
+functions using the CheckSymbolExists.cmake macro in the top-level CMakeLists
+file as follows:
+
+  # does this system provide the log and exp functions?
+  include(CheckSymbolExists)
+  set(CMAKE_REQUIRED_LIBRARIES "m")
+  check_symbol_exists(log "math.h" HAVE_LOG)
+  check_symbol_exists(exp "math.h" HAVE_EXP)
+
+Now let's add these defines to TutorialConfig.h.in so that we can use them
+from mysqrt.cxx:
+
+  // does the platform provide exp and log functions?
+  #cmakedefine HAVE_LOG
+  #cmakedefine HAVE_EXP
+
+Modify mysqrt.cxx to include math.h. Next, in the mysqrt function we can
+provide an alternate implementation based on log and exp if they are available
+on the system using the following code:
+
+  // if we have both log and exp then use them
+  #if defined(HAVE_LOG) && defined (HAVE_EXP)
+    double result = exp(log(x)*0.5);
+    std::cout << "Computing sqrt of " << x << " to be " << result << " using log" << std::endl;
+  #else
+    ...
+
+Run cmake or cmake-gui to configure the project and then build it with your
+chosen build tool.
+
+You will notice that even though HAVE_LOG and HAVE_EXP are both defined mysqrt
+isn't using them. We should realize quickly that we have forgotten to include
+TutorialConfig.h in mysqrt.cxx. We will also need to update
+MathFunctions/CMakeLists.txt with where it is located.
+
+So let's go ahead and update MathFunctions/CMakeLists.txt to look like:
+
+  add_library(MathFunctions mysqrt.cxx)
+
+  target_include_directories(MathFunctions
+            INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}
+            PRIVATE ${Tutorial_BINARY_DIR}
+            )
+
+  install(TARGETS MathFunctions DESTINATION lib)
+  install(FILES MathFunctions.h DESTINATION include)
+
+Now all we need to do is include TutorialConfig.h in mysqrt.cxx
+
+At this point you should go ahead and build the project again.
+
+Run the built Tutorial executable. Which function gives better results now,
+Step1’s sqrt or Step5’s mysqrt?
+
+Exercise: Why is it important that we configure TutorialConfig.h.in after the
+checks for HAVE_LOG and HAVE_EXP? What would happen if we inverted the two?
+
+Exercise: Is there a better place for us to save the HAVE_LOG and HAVE_EXP
+values other than in TutorialConfig.h?

+# Adding a Custom Command and Generated File #
+
+In this section we will show how you can add a generated source file into the
+build process of an application. For this example, we will create a table of
+precomputed square roots as part of the build process, and then compile that
+table into our application.
+
+To accomplish this, we first need a program that will generate the table. In the
+MathFunctions subdirectory a new source file named MakeTable.cxx will do just that.
+
+  // A simple program that builds a sqrt table
+  #include <iostream>
+  #include <fstream>
+  #include <cmath>
+
+  int main (int argc, char *argv[])
+  {
+    // make sure we have enough arguments
+    if (argc < 2)
+      {
+      return 1;
+      }
+
+    std::ofstream fout(argv[1],std::ios_base::out);
+    const bool fileOpen = fout.is_open();
+    if(fileOpen)
+      {
+      fout << "double sqrtTable[] = {" << std::endl;
+      for (int i = 0; i < 10; ++i)
+        {
+        fout << sqrt(static_cast<double>(i)) << "," << std::endl;
+        }
+      // close the table with a zero
+      fout << "0};" << std::endl;
+      fout.close();
+      }
+    return fileOpen ? 0 : 1; // return 0 if wrote the file
+  }
+
+Note that the table is produced as valid C++ code and that the output filename
+is passed in as an argument.
+
+The next step is to add the appropriate commands to MathFunctions’ CMakeLists
+file to build the MakeTable executable and then run it as part of the build
+process. A few commands are needed to accomplish this, as shown below:
+
+  # first we add the executable that generates the table
+  add_executable(MakeTable MakeTable.cxx)
+
+  # add the command to generate the source code
+  add_custom_command(
+    OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/Table.h
+    COMMAND MakeTable ${CMAKE_CURRENT_BINARY_DIR}/Table.h
+    DEPENDS MakeTable
+    )
+
+  # add the main library
+  add_library(MathFunctions
+              mysqrt.cxx
+              ${CMAKE_CURRENT_BINARY_DIR}/Table.h
+              )
+
+  target_include_directories(MathFunctions
+          INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}
+          PUBLIC ${Tutorial_BINARY_DIR}
+                 # add the binary tree directory to the search path for include files
+                 ${CMAKE_CURRENT_BINARY_DIR}
+          )
+
+  install(TARGETS MathFunctions DESTINATION lib)
+  install(FILES MathFunctions.h DESTINATION include)
+
+First, the executable for MakeTable is added as any other executable would be
+added. Then we add a custom command that specifies how to produce Table.h by
+running MakeTable. Next we have to let CMake know that mysqrt.cxx depends on
+the generated file Table.h. This is done by adding the generated Table.h to the
+list of sources for the library MathFunctions. We also have to add the current
+binary directory to the list of include directories so that Table.h can be
+found and included by mysqrt.cxx.
+
+Now let's use the generated table. First, modify mysqrt.cxx to include Table.h.
+Next, we can rewrite the mysqrt function to use the table:
+
+  if (x <= 0)
+      {
+      return 0;
+      }
+
+  // use the table to help find an initial value
+  double result = x;
+  if (x >= 1 && x < 10)
+    {
+    result = sqrtTable[static_cast<int>(x)];
+    }
+
+  // do ten iterations
+  for (int i = 0; i < 10; ++i)
+    {
+    if (result <= 0)
+      {
+      result = 0.1;
+      }
+    double delta = x - (result*result);
+    result = result + 0.5*delta/result;
+    std::cout << "Computing sqrt of " << x << " to be " << result << std::endl;
+    }
+
+Run cmake or cmake-gui to configure the project and then build it with your
+chosen build tool. When this project is built it will first build the MakeTable
+executable. It will then run MakeTable to produce Table.h. Finally, it will
+compile mysqrt.cxx which includes Table.h to produce the MathFunctions library.

+# Building an Installer #
+
+Next suppose that we want to distribute our project to other people so that they
+can use it. We want to provide both binary and source distributions on a variety
+of platforms. This is a little different from the install we did previously in
+the Installing and Testing section (Step 4), where we were installing the
+binaries that we had built from the source code. In this example we will be
+building installation packages that support binary installations and package
+management features. To accomplish this we will use CPack to create platform
+specific installers. Specifically we need to add a few lines to the bottom of
+our top-level CMakeLists.txt file.
+
+  include(InstallRequiredSystemLibraries)
+  set(CPACK_RESOURCE_FILE_LICENSE "${CMAKE_CURRENT_SOURCE_DIR}/License.txt")
+  set(CPACK_PACKAGE_VERSION_MAJOR "${Tutorial_VERSION_MAJOR}")
+  set(CPACK_PACKAGE_VERSION_MINOR "${Tutorial_VERSION_MINOR}")
+  include(CPack)
+
+That is all there is to it. We start by including InstallRequiredSystemLibraries.
+This module will include any runtime libraries that are needed by the project
+for the current platform. Next we set some CPack variables to where we have
+stored the license and version information for this project. The version
+information makes use of the variables we set earlier in this tutorial. Finally
+we include the CPack module which will use these variables and some other
+properties of the system you are on to setup an installer.
+
+The next step is to build the project in the usual manner and then run CPack
+on it. To build a binary distribution you would run:
+
+  cpack
+
+To create a source distribution you would type:
+
+  cpack -C CPackSourceConfig.cmake
+
+Alternatively, run “make package” or right click the Package target and
+“Build Project” from an IDE.
+
+Run the installer executable found  in the binary directory. Then run the
+installed executable and verify that it works.

+# Adding Support for a Dashboard #
+
+Adding support for submitting our test results to a dashboard is very easy. We
+already defined a number of tests for our project in the earlier steps of this
+tutorial. We just have to run those tests and submit them to a dashboard. To
+include support for dashboards we include the CTest module in our top-level
+CMakeLists.txt.
+
+Replace:
+  # enable testing
+  enable_testing()
+
+With:
+  # enable dashboard scripting
+  include(CTest)
+
+The CTest module will automatically call enable_testing(), so
+we can remove it from our CMake files.
+
+We will also need to create a CTestConfig.cmake file where we can specify the
+name of the project and where to submit the dashboard.
+
+  set(CTEST_PROJECT_NAME "CMakeTutorial")
+  set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
+
+  set(CTEST_DROP_METHOD "http")
+  set(CTEST_DROP_SITE "my.cdash.org/")
+  set(CTEST_DROP_LOCATION "/submit.php?project=CMakeTutorial")
+  set(CTEST_DROP_SITE_CDASH TRUE)
+
+CTest will read in this file when it runs. To create a simple dashboard you can
+run cmake or cmake-gui to configure the project, but do not build it yet.
+Instead, change directory to the binary tree, and then run:
+ 'ctest [-VV] –D Experimental'. On Windows, build the EXPERIMENTAL target.
+
+Ctest will build and test the project and submit results to the Kitware public
+dashboard. The results of your dashboard will be uploaded to Kitware's public
+dashboard here: https://my.cdash.org/index.php?project=CMakeTutorial.

+# Mixing Static and Shared #
+
+In this section we will show how by using the BUILD_SHARED_LIBS variable we can
+control the default behavior of add_library, and allow control over how
+libraries without an explicit type ( STATIC/SHARED/MODULE/OBJECT ) are built.
+
+To accomplish this we need to add BUILD_SHARED_LIBS to the top level
+CMakeLists.txt. We use the option command as it allows users to optionally
+select if the value should be On or Off.
+
+Next we are going to refactor MathFunctions to become a real library that
+encapsulates using mysqrt or sqrt, instead of requiring the calling code
+to do this logic. This will also mean that USE_MYMATH will not control building
+MathFuctions, but instead will control the behavior of this library.
+
+The first step is to update the starting section of the top level CMakeLists.txt
+to look like:
+
+  cmake_minimum_required(VERSION 3.3)
+  project(Tutorial)
+
+  # control where the static and shared libraries are built so that on windows
+  # we don't need to tinker with the path to run the executable
+  set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY "${PROJECT_BINARY_DIR}")
+  set(CMAKE_LIBRARY_OUTPUT_DIRECTORY "${PROJECT_BINARY_DIR}")
+
+  set(CMAKE_CXX_STANDARD 11)
+  set(CMAKE_CXX_STANDARD_REQUIRED True)
+
+  option(BUILD_SHARED_LIBS "Build using shared libraries" ON)
+
+  # the version number.
+  set(Tutorial_VERSION_MAJOR 1)
+  set(Tutorial_VERSION_MINOR 0)
+
+  # configure a header file to pass the version number only
+  configure_file(
+    "${PROJECT_SOURCE_DIR}/TutorialConfig.h.in"
+    "${PROJECT_BINARY_DIR}/TutorialConfig.h"
+    )
+
+  # add the MathFunctions library
+  add_subdirectory(MathFunctions)
+
+  # add the executable
+  add_executable(Tutorial tutorial.cxx)
+  target_link_libraries(Tutorial PUBLIC MathFunctions)
+
+Now that we have made MathFunctions always be used, we will need to update
+the logic of that library. So, in MathFunctions/CMakeLists.txt we need to
+create a SqrtLibrary that will conditionally be built when USE_MYMATH is
+enabled. Now, since this is a tutorial, we are going to explicitly require
+that SqrtLibrary is built statically.
+
+The end result is that MathFunctions/CMakeLists.txt should look like:
+
+  # add the library that runs
+  add_library(MathFunctions MathFunctions.cxx)
+
+  # state that anybody linking to us needs to include the current source dir
+  # to find MathFunctions.h, while we don't.
+  target_include_directories(MathFunctions
+                             INTERFACE ${CMAKE_CURRENT_SOURCE_DIR}
+                             )
+
+  # should we use our own math functions
+  option(USE_MYMATH "Use tutorial provided math implementation" ON)
+  if(USE_MYMATH)
+
+    # does this system provide the log and exp functions?
+    include(CheckSymbolExists)
+    set(CMAKE_REQUIRED_LIBRARIES "m")
+    check_symbol_exists(log "math.h" HAVE_LOG)
+    check_symbol_exists(exp "math.h" HAVE_EXP)
+
+    # first we add the executable that generates the table
+    add_executable(MakeTable MakeTable.cxx)
+
+    # add the command to generate the source code
+    add_custom_command(
+      OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/Table.h
+      COMMAND MakeTable ${CMAKE_CURRENT_BINARY_DIR}/Table.h
+      DEPENDS MakeTable
+      )
+
+    # library that just does sqrt
+    add_library(SqrtLibrary STATIC
+                mysqrt.cxx
+                ${CMAKE_CURRENT_BINARY_DIR}/Table.h
+                )
+
+    # state that we depend on our binary dir to find Table.h
+    target_include_directories(SqrtLibrary PRIVATE
+                               ${CMAKE_CURRENT_BINARY_DIR}
+                               )
+
+    target_compile_definitions(MathFunctions PRIVATE "USE_MYMATH")
+    if(HAVE_LOG AND HAVE_EXP)
+      target_compile_definitions(SqrtLibrary
+                                 PRIVATE "HAVE_LOG" "HAVE_EXP")
+    endif()
+
+    target_link_libraries(MathFunctions PRIVATE SqrtLibrary)
+  endif()
+
+  # define the symbol stating we are using the declspec(dllexport) when
+  # building on windows
+  target_compile_definitions(MathFunctions PRIVATE "EXPORTING_MYMATH")
+
+  install(TARGETS MathFunctions DESTINATION lib)
+  install(FILES MathFunctions.h DESTINATION include)
+
+Next, update MathFunctions/mysqrt.cxx to use the mathfunctions and detail namespaces:
+
+  #include <iostream>
+  #include "MathFunctions.h"
+
+  // include the generated table
+  #include "Table.h"
+
+  #include <cmath>
+
+  namespace mathfunctions {
+  namespace detail {
+  // a hack square root calculation using simple operations
+  double mysqrt(double x)
+  {
+    ...
+
+    return result;
+  }
+  }
+  }
+
+We also need to make some changes in tutorial.cxx, so that it no longer uses USE_MYMATH:
+1. Always include MathFunctions.h
+2. Always use mathfunctions::sqrt
+
+Finally, update MathFunctions/MathFunctions.h to use dll export defines:
+
+  #if defined(_WIN32)
+  #if defined(EXPORTING_MYMATH)
+    #define DECLSPEC  __declspec(dllexport)
+  #else
+    #define DECLSPEC  __declspec(dllimport)
+  #endif
+  #else //non windows
+    #define DECLSPEC
+  #endif
+
+  namespace mathfunctions
+  {
+    double DECLSPEC sqrt(double x);
+  }
+
+At this point, if you build everything, you will notice that linking fails
+as we are combining a static library without position enabled code with a
+library that has position enabled code. This solution to this is to explicitly
+set the POSITION_INDEPENDENT_CODE target property of SqrtLibrary to be True no
+matter the build type.
+
+Exercise: We modified MathFunctions.h to use dll export defines. Using CMake
+documentation can you find a helper module to simplify this?
+
+Exercise: Determine what command is enabling PIC for SqrtLibrary.
+What happens if we remove said command?
