Optionally enable this infrastructure through an undocumented `CMAKE_EXPERIMENTAL_CXX_MODULE_DYNDEP` variable. Currently this is experimental and intended for use by compiler writers to implement their scanning tools. Warn as such when the feature is activated. Later when compilers provide the needed scanning tools we can enable this variable from our corresponding compiler information modules. It is never meant to be set by project code. When enabled, generate a build graph similar to what we use for Fortran module dependencies. There are some differences needed because we can scan dependencies without explicit preprocessing, and can directly compile the original source afterward.

CMake Development ***************** This directory contains documentation about development of CMake itself. It is not part of the user documentation distributed with CMake. Contributor Instructions ======================== See `CONTRIBUTING.rst`_ for instructions to contribute changes. The process for contributing changes is the same whether or not one has been invited to participate directly in upstream development. .. _`CONTRIBUTING.rst`: ../../CONTRIBUTING.rst Upstream Development ==================== CMake uses `Kitware's GitLab Instance`_ to manage development, review, and integration of changes. The `CMake Repository`_ holds the integration branches and tags. Upstream development processes are covered by the following documents: * The `CMake Review Process`_ manages integration of changes. * The `CMake Testing Process`_ drives integration testing. .. _`Kitware's GitLab Instance`: https://gitlab.kitware.com .. _`CMake Repository`: https://gitlab.kitware.com/cmake/cmake .. _`CMake Review Process`: review.rst .. _`CMake Testing Process`: testing.rst Developer Documentation ======================= CMake developer documentation is provided by the following documents: * The `CMake Source Code Guide`_. * The `CMake Documentation Guide`_. * The `CMake Experimental Features Guide`_. .. _`CMake Source Code Guide`: source.rst .. _`CMake Documentation Guide`: documentation.rst .. _`CMake Experimental Features Guide`: experimental.rst Maintainer Documentation ======================== CMake maintainer documentation is provided by the following documents: * The `CMake Maintainer Guide`_. .. _`CMake Maintainer Guide`: maint.rst
