I think the second option should be ok and not that complicated. Put the "Ignorable" in an "IgnoredComp" install component and remove this component from the list of installed components. get_cmake_property(CPACK_COMPONENTS_ALL COMPONENTS) list(REMOVE_ITEM CPACK_COMPONENTS_ALL """) see: https://cmake.org/cmake/help/v3.11/module/CPackComponent.html AFAIR you don't need to defined a component for every install because CPack already does that for you. I think that every bits installed without component specification ends-up in the trap-them-all "Unspecified" component which is automatically created by CPack. see: https://cmake.org/cmake/help/v3.11/variable/CMAKE_INSTALL_DEFAULT_COMPONENT_NAME.html Another way to do that even more simply (**if you are sure no component are defined**) would be to: 1) install ignorable in "IgnoredComp" component 2) let all other be in your default component set(CMAKE_INSTALL_DEFAULT_COMPONENT_NAME "InstallThatOnly") 3) only install your default component set(CPACK_COMPONENTS_ALL "InstallThatOnly") -- Eric
