 - KCONFIG - component Kconfig file; set by ``idf_build_component``
 - KCONFIG_PROJBUILD - component Kconfig.projbuild; set by ``idf_build_component``
 - LDFRAGMENTS - list of component linker fragment files; set from ``idf_component_register`` LDFRAGMENTS argument
+- MANAGED_PRIV_REQUIRES - list of private component dependencies added by the IDF component manager from dependencies in ``idf_component.yml`` manifest file
+- MANAGED_REQUIRES - list of public component dependencies added by the IDF component manager from dependencies in ``idf_component.yml`` manifest file
 - PRIV_INCLUDE_DIRS - list of component private include directories; set from ``idf_component_register`` PRIV_INCLUDE_DIRS on components of type LIBRARY
-- PRIV_REQUIRES - list of private component dependentices; set from ``idf_component_register`` PRIV_REQUIRES argument
+- PRIV_REQUIRES - list of private component dependentices; set from value of ``idf_component_register`` PRIV_REQUIRES argument and dependencies in ``idf_component.yml`` manifest file
 - REQUIRED_IDF_TARGETS - list of targets the component supports; set from ``idf_component_register`` EMBED_TXTFILES argument
-- REQUIRES - list of public component dependencies; set from ``idf_component_register`` REQUIRES argument
+- REQUIRES - list of public component dependencies; set from value of ``idf_component_register`` REQUIRES argument and dependencies in ``idf_component.yml`` manifest file
 - SRCS - list of component source files; set from SRCS or SRC_DIRS/EXCLUDE_SRCS argument of ``idf_component_register``
 - WHOLE_ARCHIVE - if this property is set to ``TRUE`` (or any boolean "true" CMake value: 1, ``ON``, ``YES``, ``Y``), the component library is surrounded by ``-Wl,--whole-archive``, ``-Wl,--no-whole-archive`` when linked. This can be used to force the linker to include every object file into the executable, even if the object file doesn't resolve any references from the rest of the application. This is commonly used when a component contains plugins or modules which rely on link-time registration. This property is ``FALSE`` by default. It can be set to ``TRUE`` from the component CMakeLists.txt file.
