FindMacHID.cmake

# - try to find Mac HID frameworks
#
# Cache Variables: (probably not for direct use in your scripts)
#  MACHID_CoreFoundation_LIBRARY
#  MACHID_CoreFoundation_INCLUDE_DIR
#  MACHID_IOKit_LIBRARY
#  MACHID_IOKit_INCLUDE_DIR
#  MACOSX_HID_UINT32T  (from CheckMacHIDAPI)
#
# Non-cache variables you should use in your CMakeLists.txt:
#  MACHID_DEFINITIONS
#  MACHID_LIBRARIES
#  MACHID_INCLUDE_DIRS
#  MACHID_FOUND - if this is not true, do not attempt to use this library
#
# Requires these CMake modules:
#  CheckMacHIDAPI
#  FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
