[Slackbuilds-users] (colour) moria updating and CMake template fail

[David Chmelik]

For most/all current operating systems, informal updated C++/colour 
UMoria (umoria.org, colour addition on GitHub) is considered de facto: 
official maintainer Dr. David Grabiner hasn't updated decades... even 
homesite is gone years, despite he said he'll ask for it restored.  
Finally updating moria.Slackbuild with umoria-color (originally British 
project but Americans patched current sourcecode, renamed).  I have no 
recollection where README I use came from, or if wasn't a short enough 
official so I copied Wikipedia (likely) though it's not how I'd do 
nowadays (improved). New dungeons-of-moria (umoria.org version 
color-umoria is same except colour... they work together) is CMake 
project.  However using SlackBuilds.org's CMake template fails.

         make: *** No rule to make target 'install/strip'.  Stop.

The line is: make install/strip DESTDIR=$PKG.
         Is that correct or typographical error?  Everything else but 
this is updated except linting sourcecode, package... kind of would like 
to keep historical documentation also; they changed format, but now 
looks like manpage (not included) maybe just gets compiled unless not 
used from template... is it okay to have both old and new sourcecode and 
restore manpage, etc., these newer developers ignore for annoying markdown?
