-Subject: Fix misinterpretation of Debian Policy on LIBEXECDIR
-
-Forwarded: https://gitlab.kitware.com/cmake/cmake/-/merge_requests/6607
-
-The Debian Policy builds upon FHS 3.0 and permits installing to
-/usr/libexec. While Policy does grant an additional exception for
-applications to use a single subdirectory of /usr/lib/<triplet>, this is
-not meant to replace /usr/libexec as valid target.
