Hi guys, I’m trying to wrap some existing C++ code...

Hi guys, I’m trying to wrap some existing C++ code into a kotlin multiplatform library on windows x64, but I run into a link error: error: LIBCMT.lib(std_type_info_static.obj): machine type x86 conflicts with x64.

I didn’t specify the LIBCMT.lib dependency anywhere in my build scripts, so it seems like a bug in the konan toolchain, which uses the wrong x86 version of LIBCMT.lib instead of x64 version, could anybody help me take a look into it? thanks!

The attachment is my minimum reproduce project, run the runDebugExecutableNative gradle task could reproduce it.
The C++ code static library is built by the build_xlog_windows.bat batch script.

BTW, I’m using the latest 1.8.0 kotlin version, but I also tried 1.7.21, which also didn’t work.
