What software cam is compatible with LINUXCNC?

Hello
I am, noob, that I need to learn how to machine my own parts, on a 5-axis simultaneous machine,
For example, how was the turbine nc code example made?

due to lack of space I still could not assemble my 5-axis machine, but I am trying to study the part of the cam software and the post-processing,

-Which cam software is compatible for 5 axis simultaneous linuxcnc?

-The post-processing, is it done only once for a machine? For each piece to be machined?

-where can I find study materials?

Thank you

I think most of the "magic" in 5 axis machining, is done in the CAM software. (Which can get very expensive.)

(I don't have any experience working with 5 axis machines.)

Which software is compatible?

I would think any capable of generating 5-axis g-code.
