For add_custom_command and add_custom_target it is sequential.

For execute_process:

http://www.cmake.org/cmake/help/cmake2.6docs.html#command:execute_process

  "Runs the given sequence of one or more commands with the standard
   output of each process piped to the standard input of the next.  A
   single standard error pipe is used for all processes."
