[CMake] execute_process command problem

[wim van hoydonck]

Add an output_variable to the list of arguments of execute_process if
you do not want the output of make clean to be send to stdout:

execute_process(WORKING_DIRECTORY $ENV{PP_ROOTDIR}/src
         COMMAND make clean
         RESULT_VARIABLE ret_var
         OUTPUT_VARIABLE output_var)

Greetings,

Wim
