# FindDavix
# -------
#
# Find Davix library for file management over HTTP-based protocols.
#
# Imported Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines :prop_tgt:`IMPORTED` target:
#
# ``Davix::Davix``
#   The libdavix library, if found.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``DAVIX_FOUND``
#   True if Davix has been found.
# ``DAVIX_INCLUDE_DIRS``
#   Where to find davix.hpp, etc.
# ``DAVIX_LIBRARIES``
#   The libraries to link against to use Davix.
# ``DAVIX_VERSION``
#   The version of the Davix library found (e.g. 0.6.4)
#
# Obsolete variables
# ^^^^^^^^^^^^^^^^^^
#
# The following variables may also be set, for backwards compatibility:
#
# ``DAVIX_LIBRARY``
#   where to find the DAVIX library.
# ``DAVIX_INCLUDE_DIR``
#   where to find the DAVIX headers (same as DAVIX_INCLUDE_DIRS)
#
