# cmake module for finding DOOCS
#
# By default, only the client API is included. If the component "server" is specified, also the
# server library will be used. If the component "zmq" is specified, the DOOCSdzmq library will be used as well.
#
# returns:
#   DOOCS_FOUND        : true or false, depending on whether the package was found
#   DOOCS_VERSION      : the package version
#   DOOCS_INCLUDE_DIRS : path to the include directory
#   DOOCS_LIBRARY_DIRS : path to the library directory
#   DOOCS_LIBRARIES    : list of libraries to link against
#   DOOCS_CXX_FLAGS    : Flags needed to be passed to the c++ compiler
#   DOOCS_LINK_FLAGS   : Flags needed to be passed to the linker
