Features are gated behind ``CMAKE_EXPERIMENTAL_`` variables which must be set
to specific values in order to enable their gated behaviors. Note that the
specific values will change over time to reinforce their experimental nature.
When used, a warning will be generated to indicate that an experimental
feature is in use and that the affected behavior in the project is not part of
CMake's stability guarantees.
C++20 Module APIs
=================
Variable: ``CMAKE_EXPERIMENTAL_CXX_MODULE_CMAKE_API``
Value: ``17be90bd-a850-44e0-be50-448de847d652``
In order to support C++20 modules, there are a number of behaviors that have
CMake APIs to provide the required features to build and export them from a
project.
