Congrats on the release. For fun, I tried to compile on my Mac and it has some issues if I follow the doc ... I have Xcode and I installed CMake via brew.

Must be a simple config issue. Happy to fix, if there is interest.

DEDUTTA:build dedutta$ cmake -G Ninja ../llvm -DLLVM_BUILD_EXAMPLES=ON
CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_ASM_COMPILER not set, after EnableLanguage

This is due to non install of Ninja .....

cmake -G "Unix Makefiles" ../llvm -DLLVM_BUILD_EXAMPLES=ON -DLLVM_ENABLE_PROJECTS=clang this worked for me .... followed by make, since I didn't have ninja installed

Installing ninja obviously worked for me. Hence the issue. ...
