Add support for OBJECT libraries

[cor3ntin]

We would like to be able to create cmake OBJECT libraries ( https://gitlab.kitware.com/cmake/community/-/wikis/doc/tutorials/Object-Library ) with FRUT,
as static libraries have some limitations ( objects that only defines global objects used for their side effects are not linked, for example), and we don't care about having a short lived static library, even if the cost is negligible.

Is this something you think FRUT could support?

Thanks

@cor3ntin
Thanks for using FRUT and for opening this issue!

FRUT could support many types of CMake targets, including OBJECT libraries, but this would be outside of the scope of Reprojucer.cmake.

I am working on a FindJUCE.cmake module, which would be used with find_package. It is currently in an alpha state, and I will add it to FRUT at some point, once I find it good enough.
