[YuPan via Phabricator via llvm-commits]

binsys added a comment.

ref: https://docs.microsoft.com/zh-cn/visualstudio/releases/2019/release-notes#16.4.6

ms fixed this bug without bump cl minor version.

new version info:

  _MSC_VER=1924
  _MSC_FULL_VER=192428319

cl version is [19.24.28319]

so we need use

  _MSC_FULL_VER>=192428319 

and compare CMAKE_CXX_COMPILER_VERSION with 19.24.28319
