Solved Project tool and non-cpp file extensions

I'm using the project tool to build a plugin. I'd like to reuse a library built in my regular project structure, but I'm having a bit of trouble adding it to the Project Tool structure.
Critically, it seems like source files added to a project with "Include.Win=" must have either .h or .cpp extensions. At least, all of the files I try to add with a .cc extension aren't taking.
I should also mention that I am adding files outside of the sdk directory using "../../../../../" style paths, which I know is not recommended, but has worked well for all of my .cpp files. Could this be the problem?
Before I start extensively copying and renaming, is my assumption correct? Is there no way to force the tool to add a .cc file to my project? If so, is this documented anywhere?

Regards,
Sean

Hi Sean,

I'm afraid currently the project tool does not consider .cc extensions. I'm also not aware of any option.
But I asked our development, if there might be a hidden option and otherwise it could be considered for a future version of the project tool. I'll keep you updated here.

Cheers,
Andreas

Update: Support for .cc file extension was added and will come with the next release of the project tool.

That's great, Andreas. Thanks! I'll kludge on until then.
