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() + +#============================================================================= +# Copyright 2008-2009 Kitware, Inc. +# +# Distributed under the OSI-approved BSD License (the "License"); +# see accompanying file Copyright.txt for details. +# +# This software is distributed WITHOUT ANY WARRANTY; without even the +# implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. +# See the License for more information. +#============================================================================= +# (To distribute this file outside of CMake, substitute the full +# License text for the above reference.) + +function(FIND_PACKAGE_MESSAGE pkg msg details) + # Avoid printing a message repeatedly for the same find result. + if(NOT ${pkg}_FIND_QUIETLY) + string(REPLACE "\n" "" details "${details}") + set(DETAILS_VAR FIND_PACKAGE_MESSAGE_DETAILS_${pkg}) + if(NOT "${details}" STREQUAL "${${DETAILS_VAR}}") + # The message has not yet been printed. + message(STATUS "${msg}") + + # Save the find details in the cache to avoid printing the same + # message again. + set("${DETAILS_VAR}" "${details}" + CACHE INTERNAL "Details about finding ${pkg}") + endif() + endif() +endfunction() |
