Since commit192a9182f8(FindLAPACK: MKL clean up and fix for windows, 2013-10-08, v3.0.0-rc1~538^2), FindLAPACK accidentally used FindBLAS's `BLAS_` prefix for some of its check results. Since commit5b8f69ebe9(FindBLAS: Detect implicitly linked BLAS library, 2018-08-28, v3.13.0-rc1~150^2~2), FindBLAS stores a check result in a plain `BLAS_WORKS` variable. The typo in FindLAPACK happens to cause a collision with that name. The typo was already fixed in post-3.13 development as part of other work in commit8b63265ea5(FindLAPACK: Unify internal variables related to MKL, 2018-11-18). Fix the typo in the 3.13 version of FindLAPACK to avoid the collision. Otherwise it could cause FindLAPACK to incorrectly determine that a certain library combination does not work (or incrrectly that it works). Fixes: #18860
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 && 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://gitlab.kitware.com/cmake/cmake/issues Contributing ============ See `CONTRIBUTING.rst`_ for instructions to contribute. .. _`CONTRIBUTING.rst`: CONTRIBUTING.rst
