Issues with setting compiler as g++-11/14 at CLion at macos. "Test Cmake run finished with error "

I want my Clion in MacOS compile with the g++-11 instead of Clang. When I set up the toolchain, it did not pass the test. Clion gives "Test Cmake run finished with error". This is the screen shot

And I can click "more" to check the errors.

It looks like the test ran with some clang parameters?

ChatGPT suggested that it might be the problem with environment variable path, but it looks fine to me. Here is the output from command lines about PATH:

Here is the gcc version info at my mac. Some answers suggested that gcc-11 is just an alias of clang. But according to version info, it looks like gcc-11 and gcc-14 are surely the version installed by homebrew? Sorry I am a c++ beginner and not 100% sure about this.

An answer suggested that Uninstall gcc-11 brew remove gcc-11 and use gcc-14. I brew remove gcc@11 and set gcc-14 at Clion.here is the new screen shot.]2 The error log is basically the same:

After several editing, this question is tedious to understand now. I asked a new question here: Cannot set compiler as g++-14 at CLion at macos. "Test Cmake run finished with error "
