Installing on Linux (after building)

I've successfully built LibreCAD (current "master").  My question is about how to install it.  Normally I'd do "sudo make install" at this point.  That exists, and "succeeds" in the limited sense that it doesn't produce any errors, but it doesn't appear to do anything.

All the instructions I've been able to find just say "the generated executable is at ./unix/librecad" or variants thereof -- no mention of an install procedure.  (Pages consulted:
  - https://wiki.librecad.org/index.php?title=Build_from_source
  - https://github.com/LibreCAD/LibreCAD/wiki/Build-from-source#generic-unix
)

Is there a recommended way to install globally on the system?

You should check this proceedure : https://librecad.readthedocs.io/en/latest/appx/build.html#building-on-linux
It was checked on both Debian and Ubuntu.

The Building on Linux section ends with:

If the build is successful an executable is created, ~/dev/LibreCAD-master/unix/librecad, and LibreCAD can be launched by typing:
$ ./unix/librecad &

No mention of a post-build install procedure there either.

Edited to add: To be clear, I have built it, and have run it via "./unix/librecad &" as described.  But running it out of a build directory buried deep in my open-source-projects tree is less than ideal.

Is an alias acceptable ? Opening a terminal and type a command is not much of a pain...
