Where (folder) should I install a new version of mpd?

[agent_kith]

I have compiled a new version of mpd and it installs fine on Snakeoil. However, it does not show in the media player section.  The installation points are:
==================================================================
Installing mpd to /usr/local/bin
Installing /home/music/MPD-master/systemd/system/mpd.socket to /usr/local/lib/systemd/system
Installing /home/music/MPD-master/output/release/systemd/system/mpd.service to /usr/local/lib/systemd/system
Installing /home/music/MPD-master/systemd/user/../system/mpd.socket to /usr/local/lib/systemd/user
Installing /home/music/MPD-master/output/release/systemd/user/mpd.service to /usr/local/lib/systemd/user
Installing /home/music/MPD-master/mpd.svg to /usr/local/share/icons/hicolor/scalable/apps
Installing /home/music/MPD-master/AUTHORS to /usr/local/share/doc/mpd
Installing /home/music/MPD-master/COPYING to /usr/local/share/doc/mpd
Installing /home/music/MPD-master/NEWS to /usr/local/share/doc/mpd
Installing /home/music/MPD-master/README.md to /usr/local/share/doc/mpd
====================================================================

I think I should be somewhere as user folder or home folder or such.  Can I get some guidance?

when I run "ninja install" to install the mpd what directory should I point to?

Thanks in advance!!

have a look at /var/www/players/

There are various mpd folders in there. Duplicate one of them, modify the contents to point to your local MPD, and it will show up in the list.
