I don't think so, they serve basically the same purpose as the FindFoo.cmake 
files.

Then all these projects would have to be built as one project. if you are 
careful you can write the cmake files so that they work both as separate 
projects as well as as within one "umbrella-project".
A basic rule for that would be to avoid CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR 
and use <Project>_SOURCE_DIR and <PROJECT>_BINARY_DIR.

Not sure this is what you want to do...
