-# FindPackageMessage
-# ------------------
-#
-#
-#
-# 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()
