What are the mkspecs for clang to build qt?

Question

if I want to build qt under Windows with gcc, the configure option is -platform win32-g++, but what is the option for when I want to build qt with clang?

Answer 1

There is none for the clang/windows combination. I assume one could easily modify win32-g++ to win32-clang though, following the differences between linux-g++ and linux-clang:
