Luppp dependencies Installation issue

[snapa25]

Hi, I'm pretty sure this will be down to 'user error' but I'm following your instructions trying to install Luppp on old Ubunbtu 14.04 based distro called KXStudio currently and having issue. I am comfortable enough navigating around Linux file system on command line and running provided commands but this isn't enough knowledge needed it seems for the prerequisites. (in relation to library check and using Meson)

Issue 1 - Library Check
Where it is necessary to check libraries you have listed I have used command below for all the lib names you listed (example for Jack though I use Jack so presumed I have it).
/sbin/ldconfig -p | grep jack

This went well till I got to the 2 'git clone' options for NTK. Even if I run these with Sudo, with either of the 2 command options you provided in the install instructions I get messages back shown below:
"Cloning into 'ntk'...
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists."

Issue 2 - Running Meson
Per your instructions I used terminal to navigate to top directory level (), to use the command 'meson build'. To be honest this was one I used in trust as didn't technically know what it was doing apart from what the name suggests. In any case it did not work, with output:
"No command 'meson' found,"

I wasn't entirely surprised as I hadn't any recollection of ever installing anything called Meson before. A quick google later and I found mesonbuild.com talking about projects etc but I am not a programmer don't know how to use it and of course not trying to use it for my own project, just do what is necessary to install Luppp

So if these are dependencies, I may be stuck, could any of my problems be due to the distro age I'm using? I am keen to support your project and have some back ground in software testing which I'm more than happy to give more input on bugs etc if I can get it installed :-) so any advise you can offer is appreciated.
