# 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() #============================================================================= # 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 ${pkg}_FIND_QUIETLY) string(REGEX REPLACE "[\n]" "" details "${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()
