stay away from find_library!

due to an undocumented feature of find_xxx functions in CMake, no
additional libraries may be found after the first call to a find_xxx
function that searches the prebuilt libraries folder. CMake will request
the folder contents *at most once* and libraries added by install.py
will be missed.
