# Visual Studio 12 2013

Generates Visual Studio 12 (VS 2013) project files.

For compatibility with CMake versions prior to 3.0, one may specify this generator using the name “Visual Studio 12” without the year component.

## Project Types

Only Visual C++ and C# projects may be generated. Other types of projects (JavaScript, Powershell, Python, etc.) are not supported.

## Platform Selection

The default target platform name (architecture) is `Win32`.

The `CMAKE_GENERATOR_PLATFORM` variable may be set, perhaps via the `cmake(1)` `-A` option, to specify a target platform name (architecture). For example:

- `cmake -G "Visual Studio 12 2013" -A Win32`

- `cmake -G "Visual Studio 12 2013" -A x64`

- `cmake -G "Visual Studio 12 2013" -A ARM`

For compatibility with CMake versions prior to 3.1, one may specify a target platform name optionally at the end of the generator name. This is supported only for:

`Visual Studio 12 2013 Win64`

  Specify target platform `x64`.

`Visual Studio 12 2013 ARM`

  Specify target platform `ARM`.

## Toolset Selection

The `v120` toolset that comes with Visual Studio 12 2013 is selected by default. The `CMAKE_GENERATOR_TOOLSET` option may be set, perhaps via the `cmake(1)` `-T` option, to specify another toolset.

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 this generator uses the 32-bit variant even on a 64-bit host. One may explicitly request use of either the 32-bit or 64-bit host tools by adding either `host=x86` or `host=x64` to the toolset specification. See the `CMAKE_GENERATOR_TOOLSET` variable for details.
