[CMake] Checkout specific revision from svn with ExternalProject_Add

[Jean-Christophe Fillion-Robin]

Hi Jens,

You could specify the revision using:  SVN_REVISION -r "17027"

For example:

https://github.com/Slicer/Slicer/blob/f3b155fdf266134c274c97773710f4d4e7514858/SuperBuild/External_EMSegment.cmake#L25
