I have a Qt application that runs the deploy command during installation and packaging. This works correctly when generating a Wix installer. However, when trying to create an archive, e.g. 7z, command is ran but the files placed there do not appear in the archive. Those files do correctly appear in the installer.
Below is a small illustration of the CMake file exhibiting this behaviour. This was done using CMake 3.25.2 and a simple "Hello World" executable..
The install directory in all cases contains the executable and the file deployed-files.true. The directory when using the Wix installer contains the executable and the file deployed-files.true.
The archive file only contains the executable, but does not contain the file deployed-files.true. Looking at the directory inside _CPack_Packages it contains the executable and the file deployed-files.

list(APPEND CPACK_PRE_BUILD_SCRIPTS "${CMAKE_BINARY_DIR}/package.cmake")
include(CPack)
What I would expect is that the archive file match the contents found in the _CPack_Packages directory. So that one could just extract the generated archive and have all files.
CPACK_ARCHIVE_COMPONENT_INSTALLvariable should treat files created byinstall(CODE): those files do not correspond to any component, so it is unclear which component-specific archive should contain them. If you want the archive to contain all your files, why do you ever set this variable?
