c call zig:

• example: https://ziglang.org/learn/overview/#export-functions-variables-and-types-for-c-code-to-depend-on

quickStart:

generate c header: .h

• ✅ use zig v0.6.0 to generate c header with docker image: zig v0.6.0
• ✅ generate result: src/mathtest.h
• ❕ zig v0.9+, zig build-lib -fno-stage1 -femit-h src/mathtest.zig, not working properly.

# cd this-dir/; do:
docker run --platform linux/x86_64 -v $PWD:/app euantorano/zig:0.6.0 build-lib src/mathtest.zig -femit-h

# or:
task docker:build

# or cd repo-root/; do:
➤ task to:c:docker:build
