Why the above path?

Changing the the compiler in the IDE triggers a rescan of the compiler, which
updates the FPCVer macro. If the path to the FPC sources contains the macro
FPCVer the IDE switches to it. If this directory was not yet scanned it will be
scanned now. The IDE has a cache for multiple compilers and multiple FPC source

You can switch the compiler by using the combobox in the project's options or by
using build modes.

Yes. What exactly depends on your program. For example fpcres is commonly used.
These tools are called by the compiler, not the IDE.
