[CMake] Issue with non-system gcc path

[Rainer Poisel]

Hi Mahmood,

I think there is a problem with your toolchain. Maybe there is an
environment variable (hot guess: LD_LIBRARY_PATH or something similar)
missing.

Have a look into the following files in your build directory:
  * CMakeFiles/CMakeOutput.log and
  * CMakeFiles/CMakeError.log

Maybe there is some helpful information there?

Best regards,
  Rainer
