CMAKE_SYSTEM_NAME
|
|
-----------------
|
|
|
|
The name of the operating system for which CMake is to build.
|
|
See the :variable:`CMAKE_SYSTEM_VERSION` variable for the OS version.
|
|
|
|
Note that ``CMAKE_SYSTEM_NAME`` is not set to anything by default when running
|
|
in script mode, since it's not building anything.
|
|
|
|
System Name for Host Builds
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
``CMAKE_SYSTEM_NAME`` is by default set to the same value as the
|
|
:variable:`CMAKE_HOST_SYSTEM_NAME` variable so that the build
|
|
targets the host system.
|
|
|
|
System Name for Cross Compiling
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
``CMAKE_SYSTEM_NAME`` may be set explicitly when first configuring a new build
|
|
tree in order to enable :ref:`cross compiling <Cross Compiling Toolchain>`.
|
|
In this case the :variable:`CMAKE_SYSTEM_VERSION` variable must also be
|
|
set explicitly.
