The IDE uses the default fpc, set in Tools / Options / Environment /
Files.
Every project can use its own compiler.
When you install a package, the default compiler is used.

Then it is searched via PATH.

The 'compiler' folder looks like the FPC source directory.

When you install fpc, the path should be something like
/installbasedir/lib/fpc/3.2.0/ppcarm
