This shows the paths from the installed packages:
Tools / Configure Build Lazarus / Information

This shows all paths passed to the compiler:
Project / Project Options / Show Options

This shows the paths from used packages: 
Project / Project Options / Inherited

Analog exists for packages.

Your fpc.cfg adds more paths. See View / IDE Internals / FPC Info.

You can see the search paths for a single unit in Source / Unit
Information.

The compiler reads its cfg file and the IDE reads the information from
the compiler. The cfg is global, effects everything and is specific to
your machine.
Lazarus projects and packages are meant to work cross platform. There
is no reason for Lazarus to write something to the fpc.cfg.
