No longer builds under Windows

[ghost]

Using the command 'cmake -G "Visual Studio 10"' no longer sucessfully builds under windows, with the following error:

This is obviously to do with Windows paths using the opposite slash to more compliant operating systems. It's pretty clear this just requires a string replace similar to ('', ''), but I don't know anything about cmake so I'll leave it to somebody more apt to fix it :).

The Windows-fixes branch merged in to main ~3 months ago compiles successfully under the same environment if a workaround is desired by others in the same situation :)

Please recheck with catkin 0.5.56.

Besides: using the three month old version of catkin from the branch will not work since the current master has diverged from that significantly.
