   5 # Link statically against the runtime and STL, but link dynamically against the CRT by ignoring the static CRT
   6 # lib and instead linking against the Universal CRT DLL import library. This "Hybrid" linking mechanism is
   7 # supported according to the CRT maintainer. Dynamic linking against the CRT makes the binaries a bit smaller
   8 # than they would otherwise be if the CRT, runtime, and STL were all statically linked in.
