Fix call to windows process. This now uses the correct parameters, emits the signals correctly as errors and waits for the process to finish instead of relying on NOASYNC which did not work for runas and also made it impossible to get the return code

# Parse arguments passed to a function into several lists separated by
# upper-case identifiers and options that do not have an associated list e.g.:
#
# SET(arguments
#   hello OPTION3 world
#   LIST3 foo bar
#   OPTION2
#   LIST1 fuz baz
#   )
# PARSE_ARGUMENTS(ARG "LIST1;LIST2;LIST3" "OPTION1;OPTION2;OPTION3" ${arguments})
#
# results in 7 distinct variables:
#  * ARG_DEFAULT_ARGS: hello;world
#  * ARG_LIST1: fuz;baz
#  * ARG_LIST2:
#  * ARG_LIST3: foo;bar
#  * ARG_OPTION1: FALSE
#  * ARG_OPTION2: TRUE
#  * ARG_OPTION3: TRUE
