CMake Error at CMakeLists.txt:72 (find_package):
By not providing "FindClang.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Clang", but
CMake did not find one.
Could not find a package configuration file provided by "Clang" with any of
the following names:
ClangConfig.cmake
clang-config.cmake
Add the installation prefix of "Clang" to CMAKE_PREFIX_PATH or set
"Clang_DIR" to a directory containing one of the above files. If "Clang"
provides a separate development package or SDK, be sure it has been
installed.
解决办法：
brew install llvm@13
