If the user specifies an +instance (e.g. by setting this cache entry or via the +:envvar:`CMAKE_GENERATOR_INSTANCE` environment variable), or after a default +instance is chosen when a build tree is first configured, the value will be +available in this variable. + +The value of this variable should never be modified by project code. +A toolchain file specified by the :variable:`CMAKE_TOOLCHAIN_FILE` +variable may initialize ``CMAKE_GENERATOR_INSTANCE`` as a cache entry. +Once a given build tree has been initialized with a particular value +for this variable, changing the value has undefined behavior. + +Instance specification is supported only on specific generators: + +* For the :generator:`Visual Studio 15 2017` generator (and above) + this specifies the absolute path to the VS installation directory + of the selected VS instance. + +See native build system documentation for allowed instance values. |
