So there is something very particular in your setting.

good to know, I finally had it working, but I was absorbed a couple of days 
into the actual beef of my hobbyish time-wasting project, which you can see 
summarized here ;-P:

Shortly, MuseScore can now teach me a Piano piece through a NeoPixel LED stripe 
driven through an Arduino board, coupled with a MIDI-USB converter to feed-back 
my pressed keys to MuseScore -- I thought you might have been curious to know 
:-)!
(I know, you can buy LED-enabled keyboards, but a DIY one is just different... 
:-) )
(the full set-up needs also low-latency audio on Linux though Jack painlessly 
supported in MuseScore as well, and possibly a fully preemptible and/or 
PREEMPT_RT kernel)

Back to my glitches into the excellent MuseScore software:

1) Makefile being overwritten on 'make' from root folder: AFAICR, this stopped 
once I installed the seemingly missing cmake-qt-gui package (missing despite 
the apt-get build-dep ..., so seems a problem of the .deb/Ubuntu packages)

2) cmake standard recipe (mkdir xxx; cd xxx; cmake ../): simple inspection of 
Makefile revealed that the only difference is that this way there's no 
CMAKE_BUILD_TYPE specified -- do we pick a default one in such case? (e.g., 
DEBUG); anyway, this was screwing up Makefile in root folder et al., due to 1)

3) the MuseScore version I succesfully managed to finally compile, tweak/modify 
and use, is origin/2.2 (standard Qt 5.7 from Ubuntu 17.04)

4) I still have the annoyance of the "Loading..." dialog every time I launch 
the program (that closes on explicit/manual Alt+F4 only) -- any advice into what to look 
at, to have it go away, would be appreciated

5) PREFIX now works, but SUFFIX is not honored: so 'sudo make 
PREFIX=/usr/local/mscore-git SUFFIX=-git install' gave me an installed 
/usr/local/mscore-git/bin/mscore executable

Thanks,

        T.
