## env
# You can set the following environment variables when calling make:
#
#	${ITL}VERBOSE=y${NRM}	get detailed output
#
#	${ITL}ISOLATED=y${NRM}	When using this with the build target, the build will be isolated in the
#			sense that local caches such as ${DIM}\${GOPATH}/pkg${NRM} and ${DIM}~/.cache${NRM} will not be
#			mounted into the container. Instead, according folders underneath the
#			configured build folder are used. These folders are removed when running
#			${DIM}make clean${NRM}. That way you can force a clean build/test, where all
#			dependencies are retrieved & built inside the container.
#
#	${ITL}CROSS=y${NRM}		When using this with the build target, ${ITL}MacOS${NRM} & ${ITL}Windows${NRM} binaries
#			are also built.
