Marc Chevrier 2c71d051fa Makefiles Generators: use compiler for dependencies generation
Each source compilation generates a dependencies file. These dependencies
files are consolidated in one file per target. This consolidation is done
as part of command 'cmake -E cmake_depends` launched before evaluation of
makefile dependency graph.

The consolidation uses the same approach as `CMake` dependencies management.

Fixes: #21321

CMAKE_DEPENDS_USE_COMPILER
--------------------------
.. versionadded:: 3.20
For the :ref:`Makefile Generators`, source dependencies are now, for a
selection of compilers, generated by the compiler itself. By defining this
variable with value ``FALSE``, you can restore the legacy behavior (i.e. using
``CMake`` for dependencies discovery).
