What I meant was that I hadn't used the tiOPF package until that point and had 
opted to include the paths for the tiOPF units in

Project > Compiler Options > Other Unit Files

This works for the most part, except for for the tiDefines.inc file which 
lazarus seems to have trouble locating even though the folder where the 
tiDefines.inc file resides in included in Project > Compiler Options > Other 
Unit Files.

I meant that I followed Graeme's advice and included the .lpk file for tiOPF in 
my project's "Required Packages" section, but the project was still unable to 
find the tiDefines.inc file.

The only way it seems to work is if I change the directive in the source of some 
tiOPF units from {$I tiDefines.inc} to {$I ../Core/tiDefines.inc}.
