find_package_handle_standard_args for target-only modules
When writing a new FindX.cmake module following the spirit of Modern CMake,
that is without setting any X_LIBRARY and X_INCLUDE_DIR variables,
what is the strategy regarding use of find_package_handle_standard_args?
Shall I not use find_package_handle_standard_args at all?
If yes, shall I set X_FOUND and issue any related messages myself?
Shall I use it:
find_package_handle_standard_args(X DEFAULT_MSG X_LIBRARY X_INCLUDE_DIR)
and follow with
annoying users of FindX.cmake
Shall I simply forget the Modern CMake and set the legacy style variables?
