Thanks very much @brad.king for including the fix of the CMake 3.21.0 issue that I submitted _just two days ago_ (issue #22476), by “VS: Remove cl /FS entry from flag table for v142 and v143” ([commit 8fb349a8](https://gitlab.kitware.com/cmake/cmake/-/commit/8fb349a80e3feef7d139dd4ade2a2e64e6652e5))
I’m very glad to see that it does indeed fix the Visual C++ errors that I encountered with CMake 3.21.0: [Visual Studio 2019 16.10.4 VXL fatal error C1090: PDB API call failed, error code ‘3’ · Issue #2661 · InsightSoftwareConsortium/ITK · GitHub](https://github.com/InsightSoftwareConsortium/ITK/issues/2661) I just did a new ITK VS2019 build with CMake 3.21.1, and it was entirely successful. 😃
