> Cross-compiling with `zig cc`/`zig c++` is a very useful feature.
> Here are some references how it works and why it is so nice

> What currently happens when compiling with CXX='zig c++' is the following
> {noformat}
> Building CXX object CMakeFiles/cmTC_44138.dir/testCXXCompiler.cxx.o
> /usr/local/bin/zig -o CMakeFiles/cmTC_44138.dir/testCXXCompiler.cxx.o
> -c /build/proton/app/build/CMakeFiles/CMakeTmp/testCXXCompiler.cxx
> info: Usage: zig [command] [options]
> {noformat}
> That is, it drops the `c++` part of the command line. This seems to happen
> when compiling proton-c in the check for a working C++ compiler (to
> optionally enable tests in C++)
