[CMake] Build logging

[Johny]

Hey,

I am using a Ctest script to do a continuous build, however I can't seem 
to find a way to log the output of my make system since when you give 
ctest_build(BUILD src) it is automatically logged to the build.xml in 
the Testing directory. Is there anyway i can log the output of the 
makefile that gets generated to another file ? maybe by modifying 
something in the CMakeLists ??

Cheers,
Johny
