 # Cmake macro to detect gphoto2 libraries
 #
 # This module defines
 #  Gphoto2_FOUND          - True if libgphoto2 is detected.
 #  GPHOTO2_INCLUDE_DIRS   - Path to libgphoto2 header files.
 #  GPHOTO2_LIBRARIES      - Libraries to link against to use libgphoto2.
 #  GPHOTO2_VERSION_STRING - e.g. "2.4.14"
 #  GPHOTO2_VERSION_MAJOR  - e.g. "2"
 #  GPHOTO2_VERSION_MINOR  - e.g. "4"
 #  GPHOTO2_VERSION_PATCH  - e.g. "14"

     # without calling any cleanup functions (since they are absent from libusb-0.1).

     # which causes a crash after any usb event is generated.
     # libusb1 backend does correctly call exit function, but ATM it crashes anyway.
     # Workaround is to link against libusb so that it wouldn't get unloaded.
