I guess it is because --config is a sub-option of the --build option whose expected syntax is: cmake --build <dir> [options] [-- [native-options]] In the other case the expected syntax is different: cmake [options] <path-to-existing-build> See the different expected syntaxes of the cmake command line here: https://cmake.org/cmake/help/latest/manual/cmake.1.html That said the "non working" case should probably at least warn about ignored/unused options on the command line. However, I suspect that maintaining backward compatible command line behavior while providing meaningful error messages may not be easy. CMake developers may give more precise answer on that "guess". -- Eric
