DEB package dependencies are unreasonable

[DavidZemon]

The auto-detected package dependencies are unreasonably new. For instance, the .deb file depends on libfontconfig1 v2.11.94 or newer, which is not available on Debian Stretch (newest release at the time of this writing). Surely the CMake binaries from CMake.org will run on the newest version of Debian Stretch, so this is simply package builder being a PITA.
