- #
- # 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()
- 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()
