| # 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() |
