# Global environment variables:
# GMMPROC_GEN_SOURCE_DIR  Top directory where source files are searched for.
#                         Default value: $(dirname "$0")/../../..
#                         i.e. 3 levels above this file.
# GMMPROC_GEN_BUILD_DIR   Top directory where built files are searched for.
#                         Default value: $GMMPROC_GEN_SOURCE_DIR
#
# If you use jhbuild, you can set these environment variables equal to jhbuild's
# configuration variables checkoutroot and buildroot, respectively.
# Usually you can leave GMMPROC_GEN_SOURCE_DIR undefined.
# If you have set buildroot=None, GMMPROC_GEN_BUILD_DIR can also be undefined.
