Visual Studio 16 2019 --------------------- Generates Visual Studio 16 (VS 2019) project files. Project Types ^^^^^^^^^^^^^ Only Visual C++ and C# projects may be generated. Other types of projects (JavaScript, Powershell, Python, etc.) are not supported. Instance Selection ^^^^^^^^^^^^^^^^^^ VS 2019 supports multiple installations on the same machine. The :variable:`CMAKE_GENERATOR_INSTANCE` variable may be set as a cache entry containing the absolute path to a Visual Studio instance. If the value is not specified explicitly by the user or a toolchain file, CMake queries the Visual Studio Installer to locate VS instances, chooses one, and sets the variable as a cache entry to hold the value persistently. When CMake first chooses an instance, if the ``VS160COMNTOOLS`` environment variable is set and points to the ``Common7/Tools`` directory within one of the instances, that instance will be used. Otherwise, if more than one instance is installed we do not define which one is chosen by default. Platform Selection ^^^^^^^^^^^^^^^^^^ The default target platform name (architecture) is that of the host and is provided in the :variable:`CMAKE_VS_PLATFORM_NAME_DEFAULT` variable. The :variable:`CMAKE_GENERATOR_PLATFORM` variable may be set, perhaps via the :manual:`cmake(1)` ``-A`` option, to specify a target platform name (architecture). For example: * ``cmake -G "Visual Studio 16 2019" -A Win32`` * ``cmake -G "Visual Studio 16 2019" -A x64`` * ``cmake -G "Visual Studio 16 2019" -A ARM`` * ``cmake -G "Visual Studio 16 2019" -A ARM64`` Toolset Selection ^^^^^^^^^^^^^^^^^ The ``v142`` toolset that comes with Visual Studio 16 2019 is selected by default. The :variable:`CMAKE_GENERATOR_TOOLSET` option may be set, perhaps via the :manual:`cmake(1)` ``-T`` option, to specify another toolset. .. |VS_TOOLSET_HOST_ARCH_DEFAULT| replace:: By default this generator uses the 64-bit variant on x64 hosts and the 32-bit variant otherwise. .. include:: VS_TOOLSET_HOST_ARCH.txt
