FindPkgConfig: use "library >= version" syntax instead of deprecated --atleast-version syntax
FindPkgConfig module still uses the old syntax --atleast-version <version> <pkg>
, --max-version <version> <pkg>
and --exact-version <version> <pkg>
instead of the new ways: <pkg> >= <version>
, <pkg> = <version>
and <pkg> <= <version>
.
This is at least an issue for pkgconf
which does not handle --atleast-version
and such, see upstream issue.
