[CMake] Multiple COMMANDs in EXECUTE_PROCESS

[Denis Scherbakov]

I have multiple commands specified in one EXECUTE_PROCESS call like:

EXECUTE_PROCESS(COMMAND cmd1 ... COMMAND cmd2 ... COMMAND cmd3...)

Can anybody tell me if these commands are executed sequentially or in
parallel? Also what about ADD_CUSTOM_COMMAND, .. TARGET and so on?
