CMake: Search /usr/local paths on BSD 

CMake would have trouble with some configuration tests on FreeBSD (and
presumably other BSDs) due to installed libraries being in /usr/local, but
not being in the default search path. Adding these to the default search path
fixes mbedtls and portaudio not being found, and possibly more.
