I met this too. It seems _CMAKE_OSX_SYSROOT_PATH was set to "" somewhere, but I couldn't find the exact place.

cmake version 3.23.2

I got it. Upgrading cmake to the latest version works for me.

1. upgrade via brew install cmake or brew reinstall cmake
2. remove build directory manually and rebuild again, it would work.

Thank you so much @PlinChen

It is resolved.

This may also occur due to cached CMake files if you are already on latest cmake version via homebrew. In that case just follow syq7970's advice to invoke xcode-select, and then jump to step 2 provided by PlinChen, and then build again. Wiping the build directory forces CMake to not use cached state to fail the build config step prematurely.
