By design, include_directories() only affects the current directory and any
subdirectories added with add_subdirectory().
If "A" and "B" are built in the same CMakeLists.txt they will have the same
include paths. If this is a problem the easiest way to solve the problem is
to build them in separate directories. If B is built in a subdirectory of A
it will inherit A's include_directories().
Does this help at all?
