# DISTCHECK_SETUP
# ---------------
#
# Add a distcheck target to check the generated tarball.
#
# This step calls `make distdir' to generate a copy of the project without
# the git history and with the `.version' file (as it will be when an user
# will retrieve a stable version).
# Then:
# - create _build and _inst to respectively create a build and an installation
# directory.
# - copy the CMakeCache.txt file.
# - run cmake with _inst as the installation prefix
# - run make, make check, make install and make uninstall
# - remove _build and _inst.
#
# During the compilation phase, all files in the source tree are modified
# to *not* be writeable to detect bad compilation steps which tries to modify
# the source tree. Permissions are reverted at the end of the check.
#
