| # 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(X11_FOUND) |
| # ... |
| # ENDIF(X11_FOUND) |
| |
| FUNCTION(FIND_PACKAGE_MESSAGE pkg msg details) |
| # Avoid printing a message repeatedly for the same find result. |
| IF(NOT ${pkg}_FIND_QUIETLY) |
| SET(DETAILS_VAR FIND_PACKAGE_MESSAGE_DETAILS_${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. |
