I think use execute_process to execute a command like
perl -MSys::CPU -e ""
So, something like
execute_process(COMMAND ${PERL_EXECUTABLE} -MSys::CPU -e ""
ERROR_QUIET RESULT_VARIABLE status)
if ${status} is zero then the module exists, otherwise it doesn't. You
can wrap it in a function,
obviously.
