Hm ..
I am actually working on something more specific (see below). But as usual: I grep it from the net and it does not work :-(.

"hostname" is found, "date" and "time" is not found under windows even if it is available on the command line - very strange!?

ENDIF ( "${CMAKE_SYSTEM_NAME}" MATCHES "linux" )
