Classification: UNCLASSIFIED Caveats: NONE Thanks for sharing. I guess I originally wanted to ask if there is a switch to cmake that will allow picking 64-bit by default if 64-bit version is available.
My understanding is that (for VS2013 Express), if you run things from a VS2013 x64 Cross Tools Command Prompt, you will get environment setup for doing all things 64-bit and you will get "Visual Studio 12 2013 Win64" as default generator when you run cmake from that command prompt. And if you run from within "Developer Command Prompt for VS2013" command prompt, you will get all the 32-bit environment setup and get "Visual Studio 12 2013" as default generator. However, for CMakeLists.txt in the openmpi-1.4.4 project, it is not picking up "Visual Studio 12 2013 Win64" generator by default even if you run cmake from a VS2013 x64 Cross Tools Command Prompt. Most of my other cmakefied projects will pick "Visual Studio 12 2013 Win64" as default generator when ran from within VS2013 x64 Cross Tools Command Prompt. But if I have to specifically include the switch -G "Visual Studio 12 2013 Win64" to get the 64-bit project, I am also ok with it.

I consider this extremely annoying. I only have 1 Visual Studio version installed so it can't be picking up other versions. > -G "Visual Studio 12 2013 Win64" I always have to use that switch. Aside from picking 64-bit by default or getting a project generator that correctly allows switching within the project, I wish there was a way I could just request 64-bit with a command line switch independently of the Visual Studio version. In the case where I am working with people with different versions of Visual Studio and we share build scripts, I have no easy way of controlling 64-bit without knowing exactly which Visual Studio version is installed.
