-- Do not use CMAKE_C_FLAGS_RELEASE flags when CMAKE_BUILD_TYPE is empty if CMAKE_BUILD_TYPE was not set the generator would use Release settings this does not match the documented behavior of CMAKE_BUILD_TYPE -- CMAKE_C_FLAGS_<CONFIG> not used when -kernel is present Fixes issue where CMAKE_C_FLAGS_<CONFIG> is ignored when -kernel option is present as a compiler option When the -kernel option is added to an executable it uses a different set of language flags This does not occur -kernel=<type> is used or if it is added as part of a link flag The variables CMAKE_<LANG>_GHS_KERNEL_FLAGS_<CONFIG> are removed NOTE: By default this only added the flag -ldebug which links in the debugger library. -- Separate compiler options by newlines
CMake ***** Introduction ============ CMake is a cross-platform, open-source build system generator. For full documentation visit the `CMake Home Page`_ and the `CMake Documentation Page`_. The `CMake Community Wiki`_ also references useful guides and recipes. .. _`CMake Home Page`: https://cmake.org .. _`CMake Documentation Page`: https://cmake.org/cmake/help/documentation.html .. _`CMake Community Wiki`: https://gitlab.kitware.com/cmake/community/wikis/home CMake is maintained and supported by `Kitware`_ and developed in collaboration with a productive community of contributors. .. _`Kitware`: http://www.kitware.com/cmake License ======= CMake is distributed under the OSI-approved BSD 3-clause License. See `Copyright.txt`_ for details. .. _`Copyright.txt`: Copyright.txt Building CMake ============== Supported Platforms ------------------- * Microsoft Windows * Apple macOS * Linux * FreeBSD * OpenBSD * Solaris * AIX Other UNIX-like operating systems may work too out of the box, if not it should not be a major problem to port CMake to this platform. Subscribe and post to the `CMake Users List`_ to ask if others have had experience with the platform. .. _`CMake Users List`: https://cmake.org/mailman/listinfo/cmake Building CMake from Scratch --------------------------- UNIX/Mac OSX/MinGW/MSYS/Cygwin ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ You need to have a C++ compiler (supporting C++11) and a ``make`` installed. Run the ``bootstrap`` script you find in the source directory of CMake. You can use the ``--help`` option to see the supported options. You may use the ``--prefix=<install_prefix>`` option to specify a custom installation directory for CMake. You can run the ``bootstrap`` script from within the CMake source directory or any other build directory of your choice. Once this has finished successfully, run ``make`` and ``make install``. In summary:: $ ./bootstrap && make && sudo make install Windows ^^^^^^^ You need to download and install a binary release of CMake in order to build CMake. You can get these releases from the `CMake Download Page`_. Then proceed with the instructions below. .. _`CMake Download Page`: https://cmake.org/cmake/resources/software.html Building CMake with CMake ------------------------- You can build CMake as any other project with a CMake-based build system: run the installed CMake on the sources of this CMake with your preferred options and generators. Then build it and install it. For instructions how to do this, see documentation on `Running CMake`_. .. _`Running CMake`: https://cmake.org/cmake/help/runningcmake.html To build the documentation, install `Sphinx`_ and configure CMake with ``-DSPHINX_HTML=ON`` and/or ``-DSPHINX_MAN=ON`` to enable the "html" or "man" builder. Add ``-DSPHINX_EXECUTABLE=/path/to/sphinx-build`` if the tool is not found automatically. .. _`Sphinx`: http://sphinx-doc.org Reporting Bugs ============== If you have found a bug: 1. If you have a patch, please read the `CONTRIBUTING.rst`_ document. 2. Otherwise, please join the `CMake Users List`_ and ask about the expected and observed behaviors to determine if it is really a bug. 3. Finally, if the issue is not resolved by the above steps, open an entry in the `CMake Issue Tracker`_. .. _`CMake Issue Tracker`: https://gitlab.kitware.com/cmake/cmake/issues Contributing ============ See `CONTRIBUTING.rst`_ for instructions to contribute. .. _`CONTRIBUTING.rst`: CONTRIBUTING.rst
