Ok...
It's not a proper built-in thing, where you press 'Compile' to compile. I infact cheated.
You have to make a few batch files. I had 'build', 'build and test', 'build fxe'.
The 'test' batch also starts up geepee32 and loads the gxb.
The 'build fxe' also runs b2fxe, and doesn't test.
Anyways you set up Tools > Configure Tools... to run these batch files, then link them in as toolbar buttons.
(This is also possible on MS Visual C++)
You have to know a bit about batch files, tho, so that it works on any file anywhere.
However you -can- go into Compiler Options and set the compiler to arm-elf-gcc, add in include/lib directories, etc, which is what you're supposed to do.
