CMP0051 ------- .. versionadded:: 3.1 List :genex:`TARGET_OBJECTS` in SOURCES target property. CMake 3.0 and lower did not include the ``TARGET_OBJECTS`` :manual:`generator expression ` when returning the :prop_tgt:`SOURCES` target property. Configure-time CMake code is not able to handle generator expressions. If using the :prop_tgt:`SOURCES` target property at configure time, it may be necessary to first remove generator expressions using the :command:`string(GENEX_STRIP)` command. Generate-time CMake code such as :command:`file(GENERATE)` can handle the content without stripping. The ``OLD`` behavior for this policy is to omit ``TARGET_OBJECTS`` expressions from the :prop_tgt:`SOURCES` target property. The ``NEW`` behavior for this policy is to include ``TARGET_OBJECTS`` expressions in the output. .. |INTRODUCED_IN_CMAKE_VERSION| replace:: 3.1 .. |WARNS_OR_DOES_NOT_WARN| replace:: warns .. include:: STANDARD_ADVICE.txt .. include:: DEPRECATED.txt
