I was on 14.3 and building my project fine. After upgrading to XCode command line tools 14.3.1 (MacOS SDK 13.3), I'm unable to build my project any more: /Library/Developer/CommandLineTools/usr/bin/make build BUILD_DIR=debug -j 16 cmake --build _build/debug -j 16 ninja: error: '/Library/Developer/CommandLineTools/SDKs/MacOSX13.1.sdk/usr/lib/libz.tbd', needed by 'project1', missing and no known rule to make it make[1]: *** [build] Error 1 make: *** [debug] Error 2 NOte that the error message shows it's looking for libz.tbd still under the old SDK MacOSX13.1.sdk, while the just installed version is MacOSX13.3.sdk $ ls -lht /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk/usr/lib/libz.tbd lrwxr-xr-x 1 root wheel 10B Jun 11 21:29 /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk/usr/lib/libz.tbd -> libz.1.tbd Reinstalling cmake and ninja didn't help. I also tried reverting to the previous veresion by downloading and installing XCode command line tools 14.3, but then even more problems were found that many tools/libs were referring to MacOSX13.3.sdk instead of MacOSX13.1.sdk and reinstalling them didn't help. Can someone help please?
