What is ppc?
Where is fpc?

Lazarus supports multiple compilers.
You can either use fpc and switch the target OS and /or processor.
Or you can switch the compiler binary: Project / Project Options /
Compiler Options / Compiler Command. Replace the default
value '$(CompPath)' with the path.

You can use build modes to switch with a mouse click between various
sets of compiler options.
