========================================================================
I. Quick Step Building HDF5 Libraries with CMake Script Mode
========================================================================
This short set of instructions is written for users who want to quickly 
build the HDF5 Library and tools from the HDF5 source code package 
using the CMake tools. HDF Group recommends using a ctest script to build
HDF5.

To build HDF5 with the SZIP and ZLIB external libraries you will need to:

    1. Create a directory for your development; myhdfstuff.
    
    2. Create a directory for the HDF5 source; hdf5-1.8 in myhdfstuff.

    3. Download the SZip.tar.gz and ZLib.tar.gz to your development directory, 
       (See Section VII: APPENDIX for instructions). Both are needed if 
       building with external libraries; do not uncompress them.
       
    4. Download or create the CTestScript.cmake file in your development 
       directory, (See Section VII: APPENDIX for instructions and an example).   
          
    5. Download or create a platform configuration file in your development 
       directory, (See Section VII: APPENDIX for instructions and an example). 
       This file calls CTestScript.cmake; the platform configuration file can 
       be modified. CTestScript.cmake file should not be modified.    

    6. From your development directory execute the CTest Script with the 
       following options:

        ctest -S <configuration file>,<hdf5src> -C RelWithDebInfo -VV -O hdf5.log

    7. This will create an install package in the myhdfstuff/hdf5-1.8/build folder.

    Where:
        "configuration file" is the platform configuration file from step6;
          HDF518WindowsRWDICMake.cmake, HDF518LinuxRWDICMake.cmake, or 
          HDF518MacRWDICMake.cmake can be downloaded from the HDF Group website.
        "hdf5src" is the uncompressed HDF5 source code directory. No path 
          should be specified.
        
        The -S option uses the script version of ctest.
        
        The value for the -C option (as shown above, "-C RelWithDebInfo") must 
        match the setting for CTEST_BUILD_CONFIGURATION in the platform 
        configuration file.
        
        The -VV option is for verbose; Use -V for less verbose.
        
        The "-O hdf5.log" option saves the output to a log file hdf5.log.

========================================================================
III. Preconditions                                                           
========================================================================

   1. We suggest you obtain the latest CMake for windows from the Kitware
      web site. The HDF5 1.8.x product requires a minimum CMake version 2.8.12.                     
                                                                         
   2. If you plan to use Zlib or Szip:
      A. Download the binary packages and install them in a central location. 
         For example on Windows, create a folder extlibs and install the 
         packages there.
      B. Use source packages from an SVN server by adding the following CMake 
         options:
            HDF5_ALLOW_EXTERNAL_SUPPORT:STRING="SVN"
            ZLIB_SVN_URL:STRING="http://some_location/zlib/trunk"
            SZIP_SVN_URL:STRING="http://some_location/szip/trunk"
         where "some_location" is the URL to the SVN repository. Also set
         CMAKE_BUILD_TYPE to the configuration type.
      C. Use source packages from a compressed file by adding the following 
         CMake options:
            HDF5_ALLOW_EXTERNAL_SUPPORT:STRING="TGZ"
            ZLIB_TGZ_NAME:STRING="zlib_src.ext"
            SZIP_TGZ_NAME:STRING="szip_src.ext"
            TGZPATH:STRING="some_location"
         where "some_location" is the URL or full path to the compressed 
         file and ext is the type of compression file. Also set CMAKE_BUILD_TYPE
         to the configuration type during configuration
                                    
   3. If you are building on Apple Darwin platforms, you should add the 
      following options:
         Compiler choice - use xcode by setting the ENV variables of CC and CXX
         Shared fortran is not supported, build static:
            BUILD_SHARED_LIBS:BOOL=OFF
         Additional options:
            CMAKE_ANSI_CFLAGS:STRING=-fPIC
            CTEST_USE_LAUNCHERS:BOOL=ON
            CMAKE_BUILD_WITH_INSTALL_RPATH:BOOL=OFF         
   
   4. Windows developers should install NSIS to create an install image with CPack.
      Visual Studio Express users will not be able to package HDF5 into
      an install image executable.
   
   5. Developers can copy the config/cmake/cacheinit.cmake file and alter the
      the settings for the developers' environment. Then the only options needed
      on the command line are those options that are different. Example using HDF
      default cache file:
               cmake -C ../config/cmake/cacheinit.cmake -G "Visual Studio 11" \
               -DHDF5_ENABLE_SZIP_SUPPORT:BOOL=OFF -DHDF5_ENABLE_Z_LIB_SUPPORT:BOOL=OFF \
               -DCMAKE_BUILD_TYPE:STRING=Release ..

Notes: CMake and HDF5

   1. Using CMake for building and using HDF5 is under active development. 
      While we have attempted to provide error-free files, please 
      understand that development with CMake has not been extensively 
      tested outside of HDF. The CMake specific files may change
      before the next release.
            
   2. CMake support for HDF5 development should be usable on any 
      system where CMake is supported. Please send us any comments on 
      how CMake support can be improved on any system. Visit the 
      KitWare site for more information about CMake.
            
   3. Build and test results can be submitted to our CDash server at:
                 cdash.hdfgroup.uiuc.edu. 
      Please read the HDF and CDash document at:
                 www.hdfgroup.org/CDash/HowToSubmit. 
            
   4. See the appendix at the bottom of this file for examples of using
      a ctest script for building and testing. Using a ctest script is
      preferred because of its flexibility.
            
Notes: CMake in General

   1. More information about using CMake can be found at the KitWare site at 
      www.cmake.org.
         
   2. CMake uses the command line; however, the visual CMake tool is 
      available for the configuration step. The steps are similar for
      all the operating systems supported by CMake.



========================================================================
IV. Building HDF5 C/C++ Libraries with CMake
========================================================================

To build the HDF5 C/C++ Libraries with CMake, go through these five steps:

   1. Run CMake
   2. Configure the cache settings
   3. Build HDF5
   4. Test HDF5
   5. Packaging HDF5 (create install image)

These five steps are described in detail below.

========================================================================

   1. Run CMake

      The visual CMake executable is named "cmake-gui.exe" on Windows and should be
      available in your Start menu. For Linux, UNIX, and Mac users the
      executable is named "cmake-gui" and can be found where CMake was 
      installed. 
      
      Specify the source and build directories. 
      
      ***** Make the build and source directories different. ******
      
      For example on Windows, if the source is at c:\MyHDFstuff\hdf5, 
      then use c:\MyHDFstuff\hdf5\build or c:\MyHDFstuff\build\hdf5 as the 
      build directory.
      
      RECOMMENDED:
        Users can perform the configuration step without using the visual 
        cmake-gui program. We use the file cacheinit.cmake in the 
        config/cmake folder for our testing. This file enables all the 
        basic options and we turn specific options on or off for testing 
        using the following command line within the build directory:
        
        cmake -C <sourcepath>/config/cmake/cacheinit.cmake -G "<generator>"  [-D<options>]  <sourcepath>
        
        Where <generator> is    
            * MinGW Makefiles
            * NMake Makefiles
            * Unix Makefiles
            * Visual Studio 12
            * Visual Studio 12 Win64
            * Visual Studio 11
            * Visual Studio 11 Win64
            * Visual Studio 10
            * Visual Studio 10 Win64

        <options> is:
            * SZIP_INCLUDE_DIR:PATH=<path to szip includes directory>
            * SZIP_LIBRARY:FILEPATH=<path to szip/library file>
            * ZLIB_INCLUDE_DIR:PATH=<path to zlib includes directory>
            * ZLIB_LIBRARY:FILEPATH=<path to zlib/library file>
            * <HDF5OPTION>:BOOL=[ON | OFF]

        <cacheinit.cmake> is:
                # This is the CMakeCache file used by HDF Group for daily tests.
                ########################

                set (SZIP_PACKAGE_NAME "szip" CACHE STRING "Name of SZIP package" FORCE)

   2. Configure the cache settings

      2.1  Visual CMake users, click the Configure button. If this is the first time you are 
           running cmake-gui in this directory, you will be prompted for the 
           generator you wish to use (for example on Windows, Visual Studio 9 2008). 
           CMake will read in the CMakeLists.txt files from the source directory and 
           display options for the HDF5 project. After the first configure you 
           can adjust the cache settings and/or specify the locations of other programs.
      
           Any conflicts or new values will be highlighted by the configure
           process in red. Once you are happy with all the settings and there are no 
           more values in red, click the Generate button to produce the appropriate 
           build files. 
      
           On Windows, if you are using a Visual Studio generator, the solution and 
           project files will be created in the build folder.
      
           On linux, if you are using the Unix Makefiles generator, the Makefiles will
           be created in the build folder.

      2.2  Preferred command line example on Windows in c:\MyHDFstuff\hdf5\build directory:
      
               cmake -C ../config/cmake/cacheinit.cmake -G "Visual Studio 11" \
               -DHDF5_ENABLE_SZIP_SUPPORT:BOOL=OFF -DHDF5_ENABLE_Z_LIB_SUPPORT:BOOL=OFF \
               -DCMAKE_BUILD_TYPE:STRING=Release ..

      2.3  On Windows, if you are using a Visual Studio Express version you must 
           be sure that the following two options are correctly set/unset:
           
           HDF5_NO_PACKAGES:BOOL=ON
           HDF5_USE_FOLDERS:BOOL=OFF
           
   3. Build HDF5
   
      On Windows, you can build HDF5 using either the Visual Studio Environment 
      or the command line. The command line can be used on all platforms;
      Windows, linux, Unix, and Mac.

      To build from the command line, navigate to your build directory and
      execute the following:
          
              cmake --build . --config {Debug | Release}     
              
      NOTE: "--config {Debug | Release}" may be optional on your platform. We
            recommend choosing either Debug or Release on Windows.                                                                                      
             
      3.1  If you wish to use the Visual Studio environment, open the solution 
           file in your build directory. Be sure to select either Debug or 
           Release and build the solution.
             
      3.2.1  The external libraries (zlib and szip) can be configured
           to allow building the libraries by downloading from an SVN repository.
           The option is 'HDF5_ALLOW_EXTERNAL_SUPPORT'; by adding the following
           configuration option:
               -DHDF5_ALLOW_EXTERNAL_SUPPORT:STRING="SVN"
               
           The options to control the SVN URL (config/cmake/cacheinit.cmake file) are:
               ZLIB_SVN_URL:STRING="http://svn.hdfgroup.uiuc.edu/zlib/trunk"
               SZIP_SVN_URL:STRING="http://svn.hdfgroup.uiuc.edu/szip/trunk"
           These should be changed to your location. Also define CMAKE_BUILD_TYPE
           to be the configuration type.
           
      3.2.2  Or the external libraries (zlib and szip) can be configured
           to allow building the libraries by using a compressed file.
           The option is 'HDF5_ALLOW_EXTERNAL_SUPPORT' and is enabled by 
           adding the following configuration option:
               -DHDF5_ALLOW_EXTERNAL_SUPPORT:STRING="TGZ"
               
           The options to control the SVN URL (config/cmake/cacheinit.cmake 
           file) are:
               ZLIB_TGZ_NAME:STRING="zlib_src.ext"
               SZIP_TGZ_NAME:STRING="szip_src.ext"
               TGZPATH:STRING="some_location"
            where "some_location/xxxx_src.ext" is the URL or full path to 
            the compressed file and where ext is the type of the compression 
            file such as .bz2, .tar, .tar.gz, .tgz, or .zip. Also define
            CMAKE_BUILD_TYPE to be the configuration type.

   4. Test HDF5

      To test the build, navigate to your build directory and execute:
      
              ctest . -C {Debug | Release}
              
      NOTE: "-C {Debug | Release}" may be optional on your platform. We
            recommend choosing either Debug or Release to match the build
            step on Windows.                                                                                      

   5. Packaging HDF5 (create an install image)
   
      To package the build into a simple installer using the NullSoft installer NSIS
      on Windows, or into compressed files (.tar.gz, .sh, .zip), use the CPack tool.

      To package the build, navigate to your build directory and execute;
      
              cpack -C {Debug | Release} CPackConfig.cmake
      
      NOTE: See note 8 of this document for NSIS information.
            Also, if you are using a Visual Studio Express version or do not 
            want to enable the packaging components, set HDF5_NO_PACKAGES 
            to ON (on the command line add -DHDF5_NO_PACKAGES:BOOL=ON)
           
   6. The files that support building HDF5 with CMake are all the files in the 
      config/cmake folder, the CMakeLists.txt files in each source folder, and 
      CTestConfig.cmake. CTestConfig.cmake is specific to the internal testing 
      performed by The HDF Group. It should be altered for the user's 
      installation and needs. The cacheinit.cmake file settings are used by
      The HDF Group for daily testing. It should be altered/ignored for the user's 
      installation and needs.

   7. More information about using CMake can be found at the KitWare site, 
      www.cmake.org.
      
   8. Nullsoft Scriptable Install System
      The Nullsoft Scriptable Install System (NSIS) is an open source installation 
      system. It was created by the WinAmp authors to distribute that application, 
      but it is now a general-purpose system which anyone might use. NSIS installers 
      recognize /S for silent installation and /D=dir to specify the 
      "output directory", which is where the program will be installed. These 
      options are case-sensitive, so be sure to type them in upper case.

VI. User Defined Options for HDF5 Libraries with CMake
========================================================================

Support for User Defined macros and options has been added. The file
UserMacros.cmake has an example of the technique. In the folder,
config/cmake/UserMacros, is an implementation for Windows Visual Studio
users for linking libraries to the static CRT - Windows_MT.cmake. 

Copy the contents of the file, both macro and option, into the 
UserMacros.cmake file. Then enable the option to the CMake configuration,
build and test process.

========================================================================
VII. APPENDIX
========================================================================

Below are examples of the ctest scripts used by The HDF Group.
See the script, cmakehdf5, in the bin folder for a smaller and limited 
function shell script version of the following general scripts.
The example is for a linux machine, but the same scripts can be used on 
a Windows machine by adjusting the CTEST_CMAKE_GENERATOR option in the
product specific script.

NOTE: these files are available at the HDF web site:
    http://www.hdfgroup.org/HDF5/release/cmakebuild.html

    CTestScript.cmake
    SZip.tar.gz
    ZLib.tar.gz
    
    HDF518WindowsRWDICMake.cmake
    HDF518LinuxRWDICMake.cmake


========================================================================
CTestScript.cmake                                                       
========================================================================

The CTestScript.cmake script, shown below, is a common ctest script that 
is used to build, test, and package HDF5 Library files.
