Use lowercase method names.
Removed unneeded file.

Explicitly specifying include paths smells fishy and should be done some
other way, for example by trying to set proper prefix variables. This is
not I want to have here, as I would later have files with all possible
include path combinations.
CMAKE_STRIP doesn't exist.

Probably. Or I didn't see it be used at all.
Set also CMAKE_PREFIX_PATH in addition to CMAKE_FIND_ROOT_PATH.

Seems to help with some find_path() calls. I don't know why, but it
works. The documentation about these is awful.
Remove obsolete comment.
