- if FOAM_EXT_LIBBIN is unset and some scripts set this to /usr/lib* as a fallback (eg, to avoid an undefined value) this will cause a system library to be found before appropriate *_ARCH_PATH entry. This was noticed during a scotch compilation without third-party: resulting in the system library (/usr/lib64/libscotch.so) to be found instead of the SCOTCH_ARCH_PATH location (/usr/lib64/mpi/gcc/openmpi/lib64/). Simply changing the search order doesn't work for use, since we wish to retain a preference for any dynamic libraries discovered in a real FOAM_EXT_LIBBIN. Circumvent these issues by only taking libraries from FOAM_EXT_LIBBIN if it also points to a location within ThirdParty.
