are talking about the tests in config/testfiles? You could cross-compile them
manually, copy the executables to the target and take notes of the results. 
Then
fake the tests to return the recorded results. Shouldn't be too hard to 
automate
that with a short script.

CMake seems to have some support for cross-compiling, see
http://www.cmake.org/Wiki/CMake_Cross_Compiling. But I have no idea whether 
this
would work with CGALs CMake scripts.
