I fixed it by executing this line before cmake command.
export CXXFLAGS="-D_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION=1"

[Volodymyr B.]

Another option that is also worked is
cmake -G Xcode -Dpxr_DIR=/Users/b/Developer/USD_build -DMaterialX_DIR=/Users/b/Developer/USD_build/lib/cmake/MaterialX ..

Thanks for reporting this issue @3d4m-volodymyr, I have updated the cmake file to prevent this compilation error.
