You talking about Talon? It comes with all of the dependencies. Use ./run.sh to set the library path and ask on the Slack if there are any further issues.
(fwiw it's not skiasharp itself, it's just the mono/skia repo, which is C++)
The tarball, talon-linux.tar.xz, didn't come with a README, neither under root or /resources.
I could certainly have broken run.sh open in vim (and should have), I could have looked into /lib and found the missing dependencies, but given that there was a binary literally called talon, the general expectation is this is the binary to be linked to my PATH and run directly. Using a run.sh is not necessary when the same could be achieved by making the talon file a shell script and renaming the binary to something else.
