[Cmake] Hiding Includes

The only "automatic" include directory is supposed to be /usr/include,
which is removed by CMake.  For some reason your platform is adding
non-standard include locations automatically.  Right now there is no way
to tell cmake to know add a -I for a specific path.  A work-around until
we resolve this issue is to change all instances of /usr/local/include in
your project's CMakeCache.txt file to /usr/include.  Then CMake will
remove the -I for the directory, but the headers will still be found
because the compiler automatically looks in /usr/local/include.
