Fixed the long compile command

[Henkdetenk12345]

The old version gave alot of errors like these:

charchange.h:9:10: fatal error: wx/gdicmn.h: No such file or directory
    9 | #include "wx/gdicmn.h"
      |          ^~~~~~~~~~~~~
compilation terminated.
-bash: -I/usr/lib/x86_64-linux-gnu/wx/include/gtk3-unicode-3.2: No such file or directory

The new version fixes those issues :)
