I see that this is possible using nsis scripting: https://nsis.sourceforge.io/Add_uninstall_information_to_Add/Remove_Programs. There is also an SO post about it (from back in 2013): NSIS MUI Icon in Programs and Features

But in the CPACK NSIS generator documentation I don't see any avenue for specifying the icon in the Control Panel->Programs and Features dialog: https://cmake.org/cmake/help/latest/cpack_gen/nsis.html

CMake and CPack can produce really nice nsis installers. AFAICT this is the only thing missing!

CodePudding user response：

The CPack documentation is not very helpful.

You need to set CPACK_NSIS_INSTALLED_ICON_NAME to a .exe or .ico filename ("$INSTDIR\@CPACK_NSIS_INSTALLED_ICON_NAME@" is written to the registry)
