+# 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.
