# FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
#
# This macro is intended to be used in FindXXX.cmake modules files.
# It will print a message once for each unique find result.
# This is useful for telling the user where a package was found.
# The first argument specifies the name (XXX) of the package.
# The second argument specifies the message to display.
# The third argument lists details about the find result so that
# if they change the message will be displayed again.
# The macro also obeys the QUIET argument to the find_package command.
#
# Example:
#
#  if(X11_FOUND)
#    FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
#      "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
#  else()
#   ...
#  endif()
