+Subject: Fix RunCMake.CPack_DEB.EXTRA on Debian non-Linux OSes
+
+Forwarded: https://gitlab.kitware.com/cmake/cmake/-/merge_requests/6540
+
+The generated path with the packages uses $CPACK_TOPLEVEL_TAG, which
+by default is $CPACK_SYSTEM_NAME, thus the OS name.
+
+To make the expected stderr match also non-Linux OSes, accept any
+non-slash characters in place of "Linux", so it works also on other
+Debian OSes (e.g. Debian/Hurd).
+
+(Cherry-picked commit b07812c6de51840a0dc6d3486d4a814fa7ef37f4 from
+upstream)
