-- Adjust Spheral's third-party library discovery for FreeBSD packages.
-- Upstream hard-codes NO_DEFAULT_PATH with per-project subdirectories, while
-- FreeBSD installs CMake config files into standard prefix paths and provides
-- shared SUNDIALS targets. Also make PolyClipper install under a subdirectory
-- and set the correct Boost library variant flags.
