Yes, for native VS usage.  However, CMake in general was built originally
for single architecture builds and has a lot of infrastructure designed
before multiple-architecture environments were common.  Details of the
architecture are exposed to the imperative CMakeLists.txt code.  The
Find modules are built to find the library file corresponding to a single
architecture.  Linking is done by full path to a library file, not by
"I hope -lfoo finds the right one!", so we can't switch architectures
simply by switching the -L library search paths.

Supporting multiple architectures in a single VS project is not just a
matter of teaching the IDE project file generators to write them out.
It will require a fundamental shift in CMake's design.  That is what

is about, but it is just too much to consider with all the other major
changes going on right now.
