I can't reproduce the error. What cmake version do you use and how did you reproduce it? |

CMake 4.2.2 Configure, choose VS22 (VS26 not supported) and during configuration it threw the error (same as the one in the commit message) Edit: The original post at that I found the solution https://techoverflow.net/2019/06/20/how-to-fix-unknown-cmake-command-check_symbol_exists/ And CMake documentation does suggest it on the top before it's ran https://cmake.org/cmake/help/latest/module/CheckSymbolExists.html |

Unsure if this is the proper fix to this but for me is what worked.
