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
