Added 3D STEP file support for kicad

[groundstack]

With these changes I was able to compile kicad with support for 3D step model rendering.

#17818

I am new to void linux, first patch I submit, let's see if I am doing this properly :)

My architecture is x86_64 musl.

Looking at the log from Travis CI it timed out around 90% of the compilation job. Seems same for glibc. What's next step??

Need to do a revision bump, since this will change more than just template cosmetics and such. If a change will change functionality, or need to build in general, then do revbumps

[groundstack]

Who does the rev bump? I don't know how or if I can do it.

Arch linux includes the OCE / Step functionality by default, as it is important feature to interface with mechanical engineers.

[ndowens]

You do, by editing the template file

I've added revision number change. The bot tried to compile again, times out at 50 min where it is about 90%. How do we increase the compilation time?

[ndowens]

Can’t increase

@groundstack the recommended OpenCascade library for KiCad is the OCC one (provided by the occt package). The reason KiCad wasn't built with STEP support was due to lacking the proper CMake config flag. I'm fixing these issues in my PR, along with updating KiCad.
