CMake Fixes + Snap port to core20 (#1174)

* CMake: use PROJECT_VERSION instead of solvespace_*_VERSION

In 006539b, solvespace_MAJOR_VERSION etc. were removed.
However, these variables were still referenced in some places.
Solution: Use PROJECT_VERSION instead.

* CMake: re-add link directories for solvespace target

006539b removed the call to link_directories for gtkmm, jsonc & fontconfig.
This leads to linking errors if those libraries are in "non-standard"
paths.
Fix this by introducing a target specific target_link_directories call.

Fixes #1173

* snap: port to core20 & adapt to CMake changes

Moving to core20 was long overdue anyway, and
the recent CMake changes necessitated some fixes.
Also switch to LZO compression for (way) better cold start
performance.
