[Bf-committers] Compile Blender with cycles with Debug configuration

[tom]

Hi:

Things are more clear.
There is a bug report for CMake:
 https://cmake.org/pipermail/cmake-developers/2015-October/026737.html <https://cmake.org/pipermail/cmake-developers/2015-October/026737.html>
After some tests, the options begin with “-g” has problem too.
