CMAKE_HOST_SYSTEM
-----------------
Name of system cmake is being run on.
Composit Name of OS CMake is being run on.
The same as CMAKE_SYSTEM but for the host system instead of the target
system when cross compiling.
This variable is the composite of :variable:`CMAKE_HOST_SYSTEM_NAME` and
:variable:`CMAKE_HOST_SYSTEM_VERSION`, e.g.
``${CMAKE_HOST_SYSTEM_NAME}-${CMAKE_HOST_SYSTEM_VERSION}``. If
:variable:`CMAKE_HOST_SYSTEM_VERSION` is not set, then this variable is
the same as :variable:`CMAKE_HOST_SYSTEM_NAME`.
