Why am I getting this msys64\clang64.exe error when building? [duplicate]

Build started...
1>------ Build started: Project: ConsoleApplication6, Configuration: Debug x64 ------
1>clang-cl : error : no such file or directory: 'C:\msys64\clang64.exe'
1>Done building project "ConsoleApplication6.vcxproj" -- FAILED.
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Is msys64 something I'm supposed to have downloadeded for visual studio? I thought it might have been in my environment variables but I couldn't find it
