FindX11_XCB
-----------
Try to find the X11 XCB compatibility library.
This will define the following variables:
``X11_XCB_FOUND``
True if (the requested version of) libX11-xcb is available
``X11_XCB_VERSION``
The version of libX11-xcb (this is not guaranteed to be set even when
X11_XCB_FOUND is true)
``X11_XCB_LIBRARIES``
This can be passed to target_link_libraries() instead of the ``EGL::EGL``
target
``X11_XCB_INCLUDE_DIR``
This should be passed to target_include_directories() if the target is not
used for linking
``X11_XCB_DEFINITIONS``
This should be passed to target_compile_options() if the target is not
used for linking
If ``X11_XCB_FOUND`` is TRUE, it will also define the following imported
target:
``X11::XCB``
The X11 XCB compatibility library
In general we recommend using the imported target, as it is easier to use.
Bear in mind, however, that if the target is in the link interface of an
exported library, it must be made available by the package config file.
Since pre-1.0.0.
