The IDE searches .pp/.pas files in the FPC sources, so you should never need
to add the paths yourself.
You can force a search with Environment -> Rescan FPC source directory
If you add the -Fu option for .pp files in the FPC sources, it can happen,
that the compiler will rebuild some units. Always try to avoid that.
It is in: fpcsrc/inc/
Is it supposed to recurse sub folders?
Even if I try that, this is not working. I must add
-Fu$(LazarusDir)\fpcsrc\fcl\inc\ in Project -> Compiler Options
