Log:
[CMake] Remove unneeded and outdated policy

This was needed way back because we didn't properly handle that the SOURCES property of a target could have things that weren't source files to compile. Almost 2 years ago Takumi fixed that, and now CMake is throwing warnings that we should get off the old behavior.
