CMake already uses this when searching for FOOConfig.cmake files.
How should it behave ?
It could be done manually, i.e. every module has to have some code like that:
find_path(FOO_INCLUDE_DIR foo.h HINTS ${FOO_DIR}/include )
Same for find_library().
This wouldn't require a lot (any ?) work in cmake. But it would be a bit ugly
for searching libs (sometimes in lib, lib32 or lib64).
Or should the find_library() etc. calls check automatically whether they are
called from some FindFoo.cmake module and check for the respective variable
automatically ?
