Modules/BasicConfigVersion-SemanticVersion.cmake.in

# This is a basic version file for the Config-mode of find_package().
# It is used by write_basic_package_version_file() as input file for configure_file()
# to create a version-file which can be installed along a config.cmake file.
#
# The created file sets PACKAGE_VERSION_EXACT if the current version string and
# the requested version string are exactly the same and it sets
# PACKAGE_VERSION_COMPATIBLE if the current version is >= requested version
# and stays within the semantic-version compatibility window.
# For versions with major > 0, compatibility requires the same major version.
# For versions with major = 0, compatibility requires the same major and minor
# versions.
# The variable CVF_VERSION must be set before calling configure_file().
