[CMake] FIND_PATH finds two out of three?

[Christopher Harvey]

I'm not sure how to explain the fact that arMulti.h is reported as
located in /usr/include....I'm not sure but maybe you have to delete the
CMakeCache file...I don't think cmake has any bugs like finding files
that don't exist. Your script seems fine from what I see. Maybe you can
post a bit more? Also please keep this on the cmake mailing list.
