FindXCBΒΆ

Try to find XCB.

This is a component-based find module, which makes use of the COMPONENTS and OPTIONAL_COMPONENTS arguments to find_module. The following components are available:

XCB
ATOM         AUX          COMPOSITE    CURSOR       DAMAGE
DPMS         DRI2         DRI3         EVENT        EWMH
GLX          ICCCM        IMAGE        KEYSYMS      PRESENT
RANDR        RECORD       RENDER       RENDERUTIL   RES
SCREENSAVER  SHAPE        SHM          SYNC         UTIL
XEVIE        XF86DRI      XFIXES       XINERAMA     XINPUT
XKB          XPRINT       XTEST        XV           XVMC

If no components are specified, this module will act as though all components except XINPUT (which is considered unstable) were passed to OPTIONAL_COMPONENTS.

This module will define the following variables, independently of the components searched for or found:

XCB_FOUND
True if (the requestion version of) xcb is available
XCB_VERSION
Found xcb version
XCB_TARGETS
A list of all targets imported by this module (note that there may be more than the components that were requested)
XCB_LIBRARIES
This can be passed to target_link_libraries() instead of the imported targets
XCB_INCLUDE_DIRS
This should be passed to target_include_directories() if the targets are not used for linking
XCB_DEFINITIONS
This should be passed to target_compile_options() if the targets are not used for linking

For each searched-for components, XCB_<component>_FOUND will be set to true if the corresponding xcb library was found, and false otherwise. If XCB_<component>_FOUND is true, the imported target XCB::<component> will be defined. This module will also attempt to determine XCB_*_VERSION variables for each imported target, although XCB_VERSION should normally be sufficient.

In general we recommend using the imported targets, as they are easier to use and provide more control. Bear in mind, however, that if any 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.
