The thing is that if you ONLY want the FindXXX.cmake to look in the paths pointed by CMAKE_PREFIX_PATH, and not the standard ones (e.g., /usr, /usr/local, ... on Unix), this might not be enough. FindBoost.cmake has a very convenient variable named Boost_ROOT that specifies where the boost libraries are located. Taking a quick look at the FindQt*.cmake doc, I didn't find a similar functionality, but I still wonder if it can be achieved in a simple way. A side-comment that is tangentially related to the subject: all of our custom-made FindXXX.cmake files use the HINTS property of find_path(...) and find_library(...) (CMake >= 2.6).
