Static linking of linux audio libraries

I'm working on an audio library that's targeting both Windows and Linux. For the Windows backends I support DirectSound, WASAPI and ASIO, and for Linux it's ALSA, JACK and PulseAudio. Recently the topic of static vs. shared/dynamic linking of the c/c++ runtime (msvcrt/libc/libgcc/libstdc++) and additional dependencies came up, in light of being self-contained and library-version-independent. I decided to settle on static linking everything (DirectSound, WASAPI, ASIO and msvcrt) for Windows, because DirectSound and WASAPI are built-in, and I compile ASIO from source. But for Linux things seem a bit more complicated. This here: https://insanecoding.blogspot.com/2012/07/creating-portable-linux-binaries.html suggests I'm reasonably safe by static linking libgcc and libstdc++, but not libc itself (correct me if I'm wrong). But i have absolutely no clue about what to do with libasound, libpulse, and libjack-jackd2. APT packages even seem to provide only .so's, not .a's.

So my question basically boils down to this: how do I produce a shared library (.so) on linux, using all of libc, libgcc, libstdc++, libasound, libjack, and libpulse, while being as much self-contained as possible, require end-users to install as little as possible, and run on a as wide variety of linux distros as possible (not interested in other *NIXes).

If it makes any difference, the main goal (for now) is to publish wrapper libraries around this native binary both for .NET on nuget.org and Java on Maven central. I just want a consumer of the package to be able to say "packagereference include=audiolib" and be done with it, then be able to run on a wide range of platforms.

Really appreciate if someone from the ALSA/Pulse/JACK team can shed some light on this as there's at least some material out there on static linking GCC's runtimes, but next to nothing on the specific audio libs.
