I think you can use the Codetools Defines Editor (4th item in the Tools 
menu) to add the include path.
However, I have never figured out exactly how to do that for FPC and 
Lazarus sources which the Codetools treats specially (even though there 
is a wiki page that ought to help:
http://wiki.lazarus.freepascal.org/IDE_Window:_Codetools_Defines_Editor).
