This already exists in a form in the Tests/CMakeTests/*TestScript*
tests.

An example:
http://www.cmake.org/gitweb?p=cmake.git;a=blob;f=Tests/CMakeTests/StringTestScript.cmake;h=a562e71d38ff7db040e567f0ef9b899c2101bc9f;hb=ff1fddb0bf40b8a7170d54ccdc9420c2d7190472

Any *TestScript* file also requires a "driving" *Test.cmake.in file and 
an entry in Tests/CMakeTests/CMakeLists.txt, but the infrastructure is 
there already. Actually, there are two infrastructures in that folder, 
but this one is similar to the one you're proposing.


HTH,
