<!-- Link statically against the runtime and STL, but link dynamically against the CRT by ignoring the static CRT
lib and instead linking against the Universal CRT DLL import library. This "hybrid" linking mechanism is
supported according to the CRT maintainer. Dynamic linking against the CRT makes the binaries a bit smaller
than they would otherwise be if the CRT, runtime, and STL were all statically linked in.
See https://aka.ms/hybridcrt for more details. -->
