I'll answer this:
files_hpp = $(foreach DIR,$(subst :, ,$(VPATH)),$(wildcard $(DIR)/*.h)
files_cpp = $(foreach DIR,$(subst :, ,$(VPATH)),$(wildcard $(DIR)/*.cpp)
but I'll say that IMO this is a bad idea. I personally always recommend
that makefiles list the files they want to compile explicitly, and not
try to get them via wildcard. The latter is very error-prone: extra
files might exist and be accidentally compiled; files may be missing and
not be compiled, etc.
