With Visual Studio builds, external projects get built (by default) with the
same configuration as the outer project. If you want a different
configuration built, then you will have to customize the BUILD_COMMAND. You
can look in the source for ExternalProject.cmake to see how the default
BUILD_COMMAND is constructed and go from there.
