[CMake] How To Copy Media Files Into Out-Of-Source Build

[Karol Krizka]

Hi there,

Is there a generic way to have CMake copy (or link to) required files
(ei: movies) into an out-of-source build directory? When I build in an
out-of-source directory, I would also like to test from the same
directory without having to take any additional steps.
