I believe we move from patch to two files originally +++ b/CMakeLists.txt +++ b/cmake/LuaJITUtils.cmake to just one, in 432cdf62303b0d609525acc84b01b92ae468d327 +++ b/cmake/LuaJITUtils.cmake I expect to see a ‘v2’ in such a case - for the forthcoming patches. Anyways, if I read the correct patch above from the imun/gh-5983-fix-build-on-m1 branch then it’s LGTM with just a typo fix.
