Is there an existing issue for this feature request?

I have searched the existing issues

Currently we (as of #10906) build 5 separate test binaries and three of them bring in libslic3r, which is over a gigabyte with symbols, so just 5 test binaries are using 4.5GB of disk space and link times are annoying.

So would be nice to speed things up and save disk space by having a shared library instead.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

Build a shared library simultaneously with the static library?

Describe alternatives you've considered

Switch the Linux build to shared entirely since the only distribution method is AppImage and we can bundle them safely?

Make all builds with shared library? Would save a lot of disk space...

Additional context
