# RunCommands.cmake
#
# Run a set of commands in series.
# This is useful for creating tests which consist of more than one command.
#
# Commands are passed as -DCMD<n> as n is between 1 and 9
#
# Example Usage:
# add_test(test_name COMMAND ${CMAKE_COMMAND}
#   "-DCMD1=echo hello"
#   "-DCMD2=echo goodbye"
#   -P ${CMAKE_SOURCE_DIR}/CMake/RunCommands)
#
# An error will be throw if any command returns a non-zero exit code or if a command cannot be found.
# When an error is thrown no further commands will be executed.
#
# STDOUT and STDERR are untouched and reach output as normal.
# Before running each command is echoed to STDOUT.
