[CMake] Fw : Linking boost failure

I got boost from BoostPro. I don't need anything else I assume.
I will retry downloading.

the FindBoost is looking for a very specific filename for the boost libraries.
If your libraries are NOT named the way FindBoost is configured then FindBoost
will simply not find the libraries even though the libraries do exist.
  Did you build boost yourself or download the prebuilt libraries from
BoostPro? I think your libraries need to have at least the -d- on them for the
debug builds and also probably the boost version number in the file name also.

You can usually use a later version of boost but there are no guarantees that
some boost API was changed between the 1.34 and the 1.36 releases.

You may also want to update to the latest CMake 2.6.2 as there were some bug
fixes for the FindBoost module.
