Hello,

I’m trying to configure a project using Qt, while I try to open the project the compiler pops this error and configuration is failing.

`The current configuration mixes Clang and MSVC or some other CL compatible compiler tool. This is not supported. Use either clang or MSVC as both C and C compilers.`

Can someone help me resolve this issue?  
Thanks in Advance 🙂
