[Lazarus] CodeTools doesn't look in the project's search path

[Tobias Giesen]

Hi,

OK when I add the unit to the Project, it works much better.

I don't have to add all units that need to be found by CodeTools, I
just need to add the units in which I work and from which I look for
symbols.

But still, if CodeTools could just use the main Project path even if 
it doesn't know that the file is part of the project, that would be
nice.

Cheers,
Tobias
