Modules/BasicConfigVersion-SameMajorVersion.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,
# 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().
