I think ThirdEyeSqueegee got the ball rolling to remove fmt for cmake users in #271, I dunno how that is going

[ThirdEyeSqueegee]

@qudix yeah I'm pretty sure fmt isn't being pulled into the project anymore, we should just be able to nuke the fmt formatters

[powerof3]

I'm still getting a compile error which this fixes, I'm guessing it's because I use the original spdlog in my project vcpkg?

[qudix]

probably

[ThirdEyeSqueegee]

@powerof3 yeah if you use the custom port for spdlog in your project it won't pull fmt

[ThirdEyeSqueegee]

Merging but we should nuke the fmt formatters in the future
