[CMake] Boost system library

[Bart Janssens]

Hi all,

Not sure if this ever came up, but I'm struggling with FindBoost and
the boost system library. The system library is required from boost
1.35 onwards, but doesn't exist in earlier versions. Is there a way to
make CMake only look for the system library if the boost version is
greater than or equal to 1.35? I'm using CMake 2.6.1.

Cheers,
