[CMake] Subdirectories and FIND_LIBRARY routines

[Clifford Yapp]

Olaf,

zlib is just an example.  I'm working on building BRL-CAD, which has a
number of such libs, some of them not common at all.  Also, the
project policy is to have the libs in src/other available for local
compile at need, so that part of it isn't up to me :-/.
