These source code files can't simply be installed. You have to compile them yourself. That's something for experienced linuxers. I can't do it. If you have the knowledge, or a Linux crack available to assist or do it, you can try. Otherwise better first install the latest Mint and look what it has in it's repo. For Linux 2.1.2 is O.K.
Or search the net for a .deb file. You will need two files, the main librecad-xx.deb, and the librecad-xx-data.deb. And a bunch of dependencies, mainly qt5 files, if not already on your system.
If you have Wine installed, you might use the Windows version. Easiest the portable 2.1.3 from portableapps.com. Works well.
If you are able to get 2.2.0 Release candidate installed, then skip 2.1.3.
The .dmg file is for Mac, I think.
