Not sure.
In theory the FindFoo.cmake would have to come either with cmake or with the 
project which wants to use Foo.

CMake doesn't support additional modules directories except those set using 
the cmake variable CMAKE_MODULE_PATH (which has to be set in the cmake files 
so so the cmake script has to know before where it wants to look).

For KDE4 it works that way that a small FindKDE4.cmake comes with cmake which 
knows where to look for KDE4 and will then include the big cmake files which 
comes with KDE4.

(I guess this doesn't help a lot)
