If this is restricted to a UNIX-like environment one can use a shell script that internally executes a background job, e.g. execute_process(COMMAND sh -c "nohup p4d >/dev/null 2>&1 &") Actually the internal KWSys Process library used to implement the execute_process command does know how to create and disown daemon processes. If necessary one could teach execute_process options to trigger this behavior. In either case there is no clear way to terminate the daemon when the test is done. -Brad -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
