[CMake] Building for 64 bit with Visual Studio 2013

[Scott Aron Bloom]

That was it!  Is there any way to set that as the default?  Ie, is there an environmental variable that sets the default generator?

We have been building for 32 bits on windows, and 64 bit on linux and OSX for a while.

In order to enable this, we have a simple function that uses CMAKE_SIZEOF_VOID_P to add a define via add_defintions

However, we are now going to build for windows 64, I calling vsvarsall.bat with x64 as a parameter, however, the CMAKE_SIZEOF_VOID_P still is equal to 4.

Any idea on what Im missing?

Are you using a "Visual Studio" generator or a "Makefile" or "Ninja" generator?
The visual studio command line environment is only relevant for the later.

For the Visual Studio generators you can append e.g. "Win64" to the generator name to get the 64-bit compilers.
e.g. "Visual Studio 12 2013 Win64".
