* Fix debug build after qhull upgrade
We upgraded qhull from 8.0.1 to 8.0.2 in 504a5d3b70, which contains a commit qhull/qhull@16159c648c `use same CMake target name for Debug and non-Debug`, so this target name check is no longer required
* Fix issue like `IMPORTED_LOCATION not set for imported target "opencv_world" configuration "RelWithDebInfo".` when build Debug config
