Lets talk about libraries!

Sometimes when i try to put a game on Lutris, i find myself with a strange problem.
Some games need some specific libraries (ex:SDL SDL-MIXER…) that i can provide but i need to create another tar.gz and upload it blablabla…

I would like if there would be a command that we could do in the installation script:
Lib :
SDL
SDL-mixer

It would be easier for somebody to add a lib to his Lutris script…
I hope you understood what i was trying to say and, as usual, keep up with the great work (;
