# Find the c-ares library, and more particularly the stringprep header.

# This module defines the following variables:
#   CARES_FOUND  -  True if library and include directory are found
# If set to TRUE, the following are also defined:
#   CARES_INCLUDE_DIRS  -  The directory where to find the header file
#   CARES_LIBRARIES  -  Where to find the library file
#
# For conveniance, these variables are also set. They have the same values
# than the variables above.  The user can thus choose his/her prefered way
# to write them.
