If paths are listed but neither PATHS nor HINTS are used, this is the same as
listing the paths after the PATHS keyword.

PATH_SUFFIXES has a different purpose, so this one doesn't count here.
It adds suffixes after the base search directories, e.g. if a lib "foo"
installs headers into PREFIX/include/foo/include, PATH_SUFFIXES should be set
The HINTS keyword is relatively new, it was introduced in cmake 2.6.1, which
is required in KDE since 4.2. In KDE 4.0 and 4.1 we required cmake 2.4.5,
which didn't have the HINTS keyword.
In general I would recommend using HINTS over PATHS.

Of course, it just needs somebody to do it :-)
I'd be very happy if you help with this and start posting patches for review
to kde-buildsystem (it is important not to break source compatiblity).
