[CMake] Determine Installer Build Configuration in Visual Studio

[J Decker]

if(SUPPORTS_PARALLEL_BUILD_TYPE)

  CMAKE_INSTALL_CONFIG_NAME is set to the current configuration name
(DEbug, release, minsizerel) as chosen in the visual studio
environment.... so to choose which you build - you choose which you
build.

It doesn't package multiple configurations at once into a single NSIS,
but it will package any single configuration.

?
