Use a dedicated `std::set` for implicit include directories instead of (ab)using the emitted variable. This in combination with lambdas makes it easier to comprehend which paths are emitted. For the implicit include directories we used to omit the `CMAKE_SYSROOT_COMPILE`/`CMAKE_SYSROOT` prefix. This has been changed and the implicit paths are returned prefixed. Implicit include directory returning is only ever used by QtAutoGen which requires prefixed paths. QtAutoGen passes the (implicit) include paths to the `moc` which isn't aware of `CMAKE_SYSROOT_COMPILE`/`CMAKE_SYSROOT`.
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
