FindATKBridge
-------------

Find the ATK-SPI2 bridge headers and libraries.

Imported Targets
^^^^^^^^^^^^^^^^

``ATK::Bridge``
  The ATK SPI2 bridge library, if found.

Result Variables
^^^^^^^^^^^^^^^^

This will define the following variables in your project:

``ATKBridge_FOUND``
  true if (the requested version of) the ATK SPI2 bridge is available.
``ATKBridge_VERSION``
  the version of the ATK SPI2 bridge.
``ATKBridge_LIBRARIES``
  the libraries to link against to use the ATK SPI2 bridge.
``ATKBridge_INCLUDE_DIRS``
  where to find the ATK SPI2 bridge headers.
``ATKBridge_COMPILE_OPTIONS``
  this should be passed to target_compile_options(), if the target
  is not used for linking.
