feature: use system package for thirdparty software when available

[Trophime]

Hi,
would it be possible to use system package for thirdparty software when available?
At least on Debian/Ubuntu

No. It would be a nightmare to test it properly. Many pieces of software is not fully source-compatible either (like Sundials). It is also often compiled with the wrong flags (like skipping -fPIC when creating static libraries).
