AUTOMOC_INCLUDE_DIRECTORIES --------------------------- .. versionadded:: 4.1 Specifies zero or more include directories for AUTOMOC to pass explicitly to the Qt Meta‑Object Compiler (``moc``) instead of automatically discovering a target's include directories. When this property is set on a target, only the directories listed here will be used by :prop_tgt:`AUTOMOC`, and any other include paths will be ignored. This property may contain :manual:`generator expressions `. All directory paths in the final evaluated result **must be absolute**. If any non-absolute paths are present after generator expression evaluation, configuration will fail with an error. See also the :variable:`CMAKE_AUTOMOC_INCLUDE_DIRECTORIES` variable, which can be used to initialize this property on all targets. Example ^^^^^^^ .. code-block:: cmake add_library(myQtLib ...) set_property(TARGET myQtLib PROPERTY AUTOMOC_INCLUDE_DIRECTORIES "${CMAKE_CURRENT_SOURCE_DIR}/include/myQtLib" )
