[C++] CMake Config to get MSVC cast warning on Linux?

Are there CMake config flags or Compiler flags to get comparable errors
that our appveyor windows build use?  I seem to spend a lot of time playing
whackomole on CI after I get a CHECKIN build working locally.

Thanks,
Micah

You could also create an -m32 build on Linux which would show
additional 64->32 bit integer narrowing warnings -- little bit of a
pain to install the i386 toolchain but potentially useful.

You can try -Wconversion on gcc or clang, but IIRC it's much less smart
than MSVC and will also warn about silly things.
