# - Find the native sqlite3 includes and library

# Gphoto2_LIBRARIES, the libraries to link against to use libgphoto2
# Gphoto2_FOUND, If false, do not try to use libgphoto2.

# Gphoto2_VERSION_MAJOR, e.g. 2
# Gphoto2_VERSION_MINOR, e.g. 4
# Gphoto2_VERSION_PATCH, e.g. 14
#
# also defined, but not for general use are

# 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.
