This is new in cmake 2.6.
If you say
find_package(Foo NO_MODULE)
cmake searches for a FooConfig.cmake in a set of predefined directories, which 
are 
(lib|share)/Foo-*/cmake
and since cmake 2.6.3 also 
(lib|share)/cmake/Foo-*/

I.e. this includes all version-specific directories.

If you say 
find_package(Foo 1.2.3 NO_MODULE)
cmake will check for a FooConfigVersion.cmake file next to the FooConfig.cmake 
file which just compares the versions and has to "return" whether the version 
matches or not.
This way let's say if you have
/usr/lib/cmake/Foo-1.0.2
and 
/usr/lib/cmake/Foo-1.2.3
and you say
find_package(Foo 1.1 NO_MODULE)

cmake should find the FooConfig.cmake in lib/cmake/Foo-1.2.3/ 

This is wrapped by the FindKdepimLibs.cmake in kdelibs/cmake/modules/, which 
internally does the 
find_package/KdepimLibs NO_MODULE)
