I've faced linking issue on Win32.
qtnats considered to link cnats as a static library:
target_link_libraries(qtnats nats_static Qt::Core)
but my making process failes with 40 issues like this:

nats.cpp\build-qtnats-Desktop_Qt_5_15_2_MinGW_64_bit-Debug_deps\cnats-src\src\conn.c:2213: error: undefined reference to __imp_WSAGetLastError'
_deps/cnats-build/src/libnats_staticd.a(conn.c.obj): In function _readLoop':
nats.cpp/build-qtnats-Desktop_Qt_5_15_2_MinGW_64_bit-Debug/_deps/cnats-src/src/conn.c:2213: undefined reference to `__imp_WSAGetLastError'

And it's quite strange, due it's pointing to cnats sources, that uses WINAPI...

I've found the only way to fix it, but it's quite dumb:
Just linking WINAPI lib manualy
target_link_libraries(qtnats nats_static Ws2_32 Qt::Core)

Also, I'm writing my own C++/Qt wrapper of cnats, and faced the same problem if I use cnat as a static lib, but it causes no problems if I use NATS_BUILD_LIB_SHARED ON, unlike qtnats, where this option does't help.

I find that it is necessary to add -DCMAKE_POSITION_INDEPENDENT_CODE=ON to be able to build the *.so file. The build fails otherwise. The build was on Ubuntu 22.04 using Qt 6.5.4.
