# Creates a build directory then invokes cmake and make
# from that dir with only the specified options/targets.
# Supports projects that create DEB/RPM package files for
# upload to PackageCloud or other repository, which must
# use a system install prefix like /usr/local.  Calling
# the "install" goal with a system prefix requires sudo,
# but building a package doesn't require the install step.
# Prereqs:
# The build minion has cmake, make, gcc etc.
# Environment variables:
# WORKSPACE is a non-empty path (required)
# CMAKE_INSTALL_PREFIX is a non-empty path (required)
# BUILD_DIR is a path (optional; has usable default)
# CMAKE_OPTS has options for cmake (optional, empty default)
# MAKE_OPTS has options for make (optional, empty default)
