Out of source detection is broken

[remram44]

The BUILDINSOURCE check in the main CMakeLists.txt is broken; building in /home/vagrant/build-uvcdat when the source is in /vagrant makes it think I'm building in the source. Very annoying, since it always affects Vagrant.

@dlonie Can you look at this issue please. Probably a one line fix (but we have to be careful about the regex)

Should be fixed now. @remram44, can you let us know if this is working for you when you get a chance to try it out?

[remram44]

Yes the patch was enough for my setup.
