3 Question for today

The project I'm working on, has at least 3 developer's.
My problem here is: I'm the only one developing with TChart,
thats why I'm the only one with an TChart installation.
How could it be done, that the project can be compiled
by the users, too.
I thought about dll's or package, but did not found a solution yet.
Kind regards,
