Hi Bill, When you invoke find_library, FOO is created as a cache entry. As long as FOO has a value (i.e., not FOO_NOTFOUND) find_library will not refresh its contents on succesive runs of cmake. If you unset(FOO CACHE) and rerun cmake, then the foo library will be searched for again. Is this a good enough solution for your situation?
