# === User-settable variables ===
#
# CCACHE_BASE
# The directory where ccache is installed. The build dependency on
# devel/ccache is only added when this is ${LOCALBASE}.
#
# Default: ${LOCALBASE}
#
# CCACHE_DIR
# The directory where the cached compiler results are stored. By
# default, they are stored inside WRKDIR, so they are lost after
# a "make clean".
#
# === Package-settable variables ===
#
# IGNORE_CCACHE
# Can be set to "yes" for packages that have problems with ccache.

# Keywords: ccache
