45.beta.1 dependency of sysprof-4 doesnt exist anymore since sysprof 45.beta
I'm not a developer, so I might be wrong about this. But if I try to build the beta.1 it will fail
Run-time dependency sysprof-4 found: NO (tried pkgconfig)
mutter/meson.build:439:18: ERROR: Dependency "sysprof-4" not found, tried pkgconfig
From what I understand, this is because with sysprof 45.beta there was rewrite of it. So there is no sysprof-4 anymore, only a sysprof-6.
