- The find_* commands now provide a HINTS option.
- The option specifies paths to be preferred over the system paths.
- Many Find* modules were using two find calls with NO_DEFAULT_PATH
to approximate the behavior, but that blocked users from overriding
things with CMAKE_PREFIX_PATH.
- This commit uses the HINTS feature to get desired behavior in
only one find command call.
