The makefile is only used when called by the cmMessageCommand, so inline the use of it there. It otherwise creates an undesirable dependency on cmMakefile for issuing messages in the cmake instance, a violation of the Interface Segregation Principle. https://en.wikipedia.org/wiki/Interface_segregation_principle This also makes it more explicit that the variable definitions only affect the message() command. If an AUTHOR_WARNING is issued for any other reason, it is not affected. To affect that, it is necessary to set the cache variable instead of the regular variable. This is an unfortunate interface quirk, but one which can't be fixed easily now.
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`_. .. _`CMake Home Page`: https://cmake.org .. _`CMake Documentation Page`: https://cmake.org/cmake/help/documentation.html 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 ------------------- MS Windows, Mac OS X, Linux, FreeBSD, Solaris, HP-UX, IRIX, BeOS, QNX 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 compiler 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 && 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 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://cmake.org/Bug Contributing ============ See `CONTRIBUTING.rst`_ for instructions to contribute. .. _`CONTRIBUTING.rst`: CONTRIBUTING.rst
