# Determine program version from file "VERSION" (example: "14.1")
# The reason why this information is stored
# in a file and not as CMake variable is that CMake-unaware programs can parse
# and use it (e.g. Sphinx). Also web-based hosting frontends such as GitLab
# automatically use a file "VERSION".
#
# Variables defined::
#
#   PROGRAM_VERSION
