The languages used in compiling STATIC libraries need to be propagated to dependents regardless of the settings of INTERFACE_LINK_LIBRARIES or CMP0022. They are independent of the libraries in the link interface. Prior to commit v2.8.12~192^2~2 (Introduce the INTERFACE_LINK_LIBRARIES property, 2013-06-04) the cmTarget::ComputeLinkInterface code path for "explicitLibraries" could never be taken for STATIC libraries, so the logic to propagate languages existed only in the non-explicitLibraries code path. After that commit, INTERFACE_LINK_LIBRARIES could be set for STATIC libraries to cause the "explicitLibraries" code path to be taken. The commit also left the old non-explicitLibraries code path conditional on CMP0022 not being set to NEW. Thus link language propagation was left missing from two cases by that commit. The explicitLibraries code path was fixed to propagate languages by commit v2.8.12~149^2~1 (cmTarget: Fix iface libraries and languages for static libraries, 2013-07-26). However, the non-explicitLibraries case was never taught to propagate languages when CMP0022 is set to NEW. Fix that now. Factor the logic to propagate link languages out of the link interface libraries conditions so that it always occurs. Update Tests/Fortran to set CMP0022 to NEW to test this case (because the test passes only if link language propagation works).
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`: http://www.cmake.org .. _`CMake Documentation Page`: http://www.cmake.org/cmake/help/documentation.html CMake is maintained by `Kitware, Inc.`_ and developed in collaboration with a productive community of contributors. .. _`Kitware, Inc.`: http://www.kitware.com 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`: http://www.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 the 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`: http://www.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`: http://www.cmake.org/cmake/help/runningcmake.html Contributing ============ See `CONTRIBUTING.rst`_ for instructions to contribute. .. _`CONTRIBUTING.rst`: CONTRIBUTING.rst
