  The imported target "Qt5::Core" references the file

     "/usr/local/.//mkspecs/macx-clang"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained
