Makefile : cmake_check_build_system
Shouldn't this rather be:
Makefile: <list of CMakeLists.txt, etc>
cmake_check_build_system
?
...in which case, the only thing that should get checked is if the
CMakeLists.txt are newer than the Makefile. So in most cases this should
be fast.
We need to run cmake_check_build_system first because make can not
handle missing depend .h files. The check build system step makes sure
the current set of depends won't kill make. It is also useful for
getting around some other make limitations that I can not remember right
now.
