[CMake] EXEC_PROGRAM vs.. EXECUTE_PROCESS problem

[Alexander Neundorf]

Hi,

please have a look at the attached CMakeLists.txt. There is one call to EXEC_PROGRAM(), which works, and one call to EXECUTE_PROCESS(), where cmake complains about an unterminate string.
I didn't find a way to get this working.
Did I just miss the right way or is it a bug ?

Alex
