Yes, include directories are inherited, but you can use the BEFORE 
option to prepend.  See the documentation for the include_directories 
command.

INCLUDE_DIRECTORIES
    Add include directories to the build.

      INCLUDE_DIRECTORIES([BEFORE] dir1 dir2 ...)

    Add the given directories to those searched by the compiler for
    include files.  If BEFORE is specified, the directories are prepended
    onto the current list of directories instead of appended.
