I've set CMAKE_MODULE_PATH like this:

SET(CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake_modules"
${CMAKE_MODULE_PATH})

Shouldn't that allow cmake to search on the augmented path,
including the original default path ?

Can you explain how that include works - how will it find
GetPrerequisites, if my earlier attempts failed ?
