# This is a basic version file for the Config-mode of find_package().

# to create a version-file which can be installed along a config.cmake file.

# the requested version string are exactly the same and it sets
# PACKAGE_VERSION_COMPATIBLE if the current version is >= requested version,
# but only if the requested major version is the same as the current one.
# The variable CVF_VERSION must be set before calling configure_file().
