Missing compiler?

[stijnb1234]

I've followed the instructions, but when I run the cc_workspace.sh script, I get:

--- stderr: custom_interfaces                                                                                                                                                                            
CMake Error at CMakeLists.txt:2 (project):
  The CMAKE_C_COMPILER:

  is not a full path and was not found in the PATH.

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.
