Looks like Apple does not support statically linked binaries: https://developer.apple.com/library/archive/qa/qa1118/_index.html
I will exclude that combination from the build matrix.

If there are too many ifs and buts maybe just remove BUILD_STATIC?

Where is the fun in that? I like a challenge and I am learning a lot of new things too.

Everything is building successfully and without warnings (as far as I could see in the logs).

• the "shared" Windows builds (MINGW and MSVC) are not running, as the dll files are not found yet
• the "static" Windows builds (MSVC) only have some crashing test case (does not happen on the other compiler/platform combinartions)
• I had to comment the function call unshield_set_log_level(log_level); in unshield, because this symbol is not exported yet (seems to be related to the static int current_log_level)

I will continue after the holidays - Happy Easter holidays.
