> `libXft-devel` is already there, but what about Xcursor or Xft?

Right now there is only `libXt` (intrinsics). Xft is needed for xft font support, Xpm and Svg for additional icons format, readline for a better FvwmConsole. I don't use Xcursor but it can be useful as well.

More info for optional dependencies : https://github.com/fvwmorg/fvwm3/blob/master/dev-docs/INSTALL.md#manually
Basically they should be the same as fvwm except for Xinerama (removed support in fvwm3).
