Hello all,
I'm currently building OpenSG2 with Cg support. Our site uses a custom
location for Cg, and the FindCg.cmake script doesn't find it.
Could you include the following patch (or something with similiar
functionality) in OpenSG? The patch allows for setting an environment
variable CG_ROOT to point CMake in the right direction...
Cheers,
Johannes
