# Description:
# Control the verbosity of make commands by defining some prefixes that
# other make rules can use.
#
# Setting the environment variable BUILD_VERBOSE=1 echos the full commands
# being executed, while leaving it off echos just a short description.
# Variables:
# C1 - Prefix for the command to be executed. ex. '$(C1)$(CC) foo.C'
# C2 - Prefix for the short description of the command. ex. '$(C2)CC foo.C'
