Hello Sagar,
Missing config.h means that your include flags for wxWidgets are not
correctly set. KiCad attempts to find these using `wx-config --cppflags`.
You can run this command and see what the response is. It should include
something like:
Hi,
KiCad is not supported on this platform, so I doubt anyone can provide
step-by-step build instructions.
It sounds like you are getting stuck at the building wxWidgets stage? If
so, you probably will need to step through that cmake and see where it is
getting hung up.
> P.S. Is it possible
