Will GMod recognise source games not on steam account?

I didn’t think this was a normal question asked, so I thought I’d make my own thread. I recently just recovered my half life 2 account along with CS:S and with the whole non transferable games to new accounts I have only half life 2 and counter strike source on one single account while the rest of my games are on another account. My question is, I have CS:S and Half Life 2 installed on my pc, but if Garry’s Mod is on my other account, will I still be able to use the content from HL2 and CS:S? I really dont wanna buy Garry’s mod on an account I’m never on.

no

It can only fetch content belonging to you
