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.
