For additional search paths in which to find modules themselves there is 
CMAKE_MODULE_PATH but given your example that is I assume not what you 
are looking for.

There is CMAKE_PREFIX_PATH (environment or cmake cache variable) which 
is however intended to be used by users of a project so they can tell 
cmake about their local non standard prefixes rather than by project 
authors.

Would that fit your use case?
