| For each toolset that comes with this version of Visual Studio, there are | |
| variants that are themselves compiled for 32-bit (x86) and 64-bit (x64) hosts | |
| (independent of the architecture they target). By default Visual Studio | |
| chooses the 32-bit variant even on a 64-bit host. One may request use of the | |
| 64-bit host tools by adding a ``host=x64`` option to the toolset specification. | |
| See the :variable:`CMAKE_GENERATOR_TOOLSET` variable for details. |
