|
|||
when running the ``install`` target.
|
||||
* ``ALWAYS_BUILD_DOCS`` - BOOL. If set to ``TRUE`` and ``BUILD_DOCUMENTATION`` is ``TRUE`` then documentation for API bindings will always be built.
|
||||
Disabling this is useful for faster incremental builds. The documentation can be manually built by invoking the ``api_docs`` target.
|
||||
* ``LINK_TIME_OPTIMIZATION`` - BOOL. If set to ``TRUE`` link time optimization will be enabled.
|
||||
|
||||
On the command line these can be passed to ``cmake`` using the ``-D`` option. In ``ccmake`` and ``cmake-gui`` these can be set in the user interface.
