Sure, you can use: set(CMAKE_MODULE_PATH "/path/to/modules"). That  
path will be checked first so you can use it to override things in the  
CMake distribution too.

In my projects I put the CMake stuff that I want to distribute with my  
code into a top-level directory called CMake and use it like so:  
set(CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/CMake").

Cheers,
