#--- FindDKS ------------------------------------------------------------------

# This module defines:
#   DKS_INCLUDE_DIR, where to find DKSBaseMuSR.h
#   DKS_LIBRARY, shared library to be linked against if using DKS
#
# **as35** since I currently also maintaing the DKS library, it should add
# a DKSConfig.cmake which eventually will make this module obsolate. This 
# means this module is only a kick starter.
