Folks, it is 2022, il2cpp works great and no option to compile fwith better than c++11 for Android?!!

Is there anything specific from later C++ standards that you need to use? At least for the IL2CPP generated code, there is no need to compile with a newer version of C++.
unique_ptr for ex
Note that unique_ptr is part of C++11.
However, if you have a C++ library you would like to use, it is probably better that you compile that yourself, then you can use any compiler flags that are necessary.
