# CMakeDetermineVSServicePack

Changed in version 4.1: This module is available only if policy `CMP0196` is not set to `NEW`.

Deprecated since version 3.0: This module should no longer be used. The functionality of this module has been superseded by the `CMAKE_<LANG>_COMPILER_VERSION` variable that contains the compiler version number.

This module provides a command to determine the installed Visual Studio service pack version for Visual Studio 2012 and earlier.

Load this module in a CMake project with:

    include(CMakeDetermineVSServicePack)

## Commands

This module provides the following command:

DetermineVSServicePack

  Determines the Visual Studio service pack version of the `cl` compiler in use:

      DetermineVSServicePack(<variable>)

  The result is stored in the specified internal cache variable `<variable>`, which is set to one of the following values, or to an empty string if the service pack cannot be determined:

  - `vc80`, `vc80sp1`

  - `vc90`, `vc90sp1`

  - `vc100`, `vc100sp1`

  - `vc110`, `vc110sp1`, `vc110sp2`, `vc110sp3`, `vc110sp4`

## Examples

Determining the Visual Studio service pack version in a project:

    if(MSVC)
      include(CMakeDetermineVSServicePack)
      DetermineVSServicePack(my_service_pack)
      if(my_service_pack)
        message(STATUS "Detected: ${my_service_pack}")
      endif()
    endif()
