No trick, but to avoid this, perhaps we should change the "--build"
handler to run the cmake configure & generate step before calling out
to MSBuild. You can easily do this yourself from the command line by
adopting the pattern:

  cmake . && cmake --build . --config Release

This is a good idea for a feature request. Not sure if we should just
always do that by default and provide a way to turn off with a
"--no-regenerate", or vice-versa with a "--please-generate-first" ...
:-)


HTH,
