Bug 421362

SUMMARY
The package name passed to `find_package_handle_standard_args` (XCB_XKB) does not match the name of the calling package (XCB).

STEPS TO REPRODUCE
1. find_package(XCB REQUIRED COMPONENTS XCB XKB)


OBSERVED RESULT
CMake Warning (dev) at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:272 (message):
  The package name passed to `find_package_handle_standard_args` (XCB_XCB)
  does not match the name of the calling package (XCB).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.
