# This is a CMake version file for the Config-mode of find_package().
#
# The version constraint is compatible with the current package under the
# following conditions:
# - If a version range is specified, the package version falls within the
# range up to the supplied version components.
# - If a single version is specified, the current package version matches
# only the requested version components.
#
# Examples:
# - 3...5 matches 3.0.0.0 to <6.0.0.0
# - 3...<5 matches 3.0.0.0 to <5.0.0.0
# - 3...<5.1 matches 3.0.0.0 to <5.1.0.0
# - 3 matches 3.0.0.0 to <4.0.0.0
# - 3.4 matches 3.4.0.0 to <3.5.0.0
