OK, thanks 😕

**IMHO** : It is too complicated! 🤯  
see too [CMake Error: install(EXPORT "ProjectTargets" ...) includes target "xxx" which requires target "yyy" that is not in any export set.](https://discourse.cmake.org/t/cmake-error-install-export-projecttargets-includes-target-xxx-which-requires-target-yyy-that-is-not-in-any-export-set/7344)
