The scan step may need to output additional information for the
compiler, not just the build tool. The modmap is assumed to be beside
the object output. Additional refactoring may open up a channel to
inform per-source paths to the dyndep rule in the future, but is not
done here.
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.

The change in commit 901386f646 (cmake-mode.el: Add navigation by
function and macro, 2020-12-11) introduced a regression. Emacs 26 could
not load cmake-mode.el anymore. Use `(not-char ")")`, not `(not ")")`.

Since 3.19, CMake generates a deprecation warning when using a minimum
version less than 2.8.12. This eliminates those warnings generated
during tests, which are typically hidden from the user and developer but
are being generated nonetheless.
