subsurface/scripts/smtk2ssrf-build.sh

#!/bin/bash
# This script is meant to run from src directory in the same fashion than
# subsurface/scripts/build.sh
#
# Flags:	-c (--cli) Build commandline version (no graphics)
#		-t (--tag) A git valid tag, commit, etc in subsurface tree
#		-j (--jobs) Desired build parallelism, integer.
#		-b (--build) Cmake build type, valid values Debug or Release
#		-y Assume "yes" in prompt. Useful in automated builds
# Examples:
#     $	./subsurface/scripts/build-smtk2ssrf.sh
#	No flags, will build a Release version, with -j4 parallelism in the
#	last set git tree position. This should be the usual use form.
#     $	./subsurface/scripts/build-smtk2ssrf.sh -j 2 -t v4.6.5 -b Debug
#	Will build a Debug version of smtk2ssrf from the tag v4.6.5 (proved it
#	exists) with -j2 parallelism.
#

# Default build parallelism
#
JOBS="-j4"

# Default subsurface git tag: none, assume last manually selected
# or set in build.sh
#
SSRF_TAG=""

# Default build type Release
#
RELEASE=Release
