How to add file to the project based on condition or variable value?

[alexzfirm]

I have one project that is used to build 5 different installers.

I have 5 different help files (with different names). I need to have only 1 per build. How can I add (or remove) files from the project based on variable value or some other condition?

Thank you

You might be able to use a build variable for this. (Build > Settings > Variables tab.)

Build variables are essentially preprocessor definitions that get replaced when the project is compiled.

Thank you that worked. The filename containing variable shows in red in the file list but still compiles and installs just fine.
