Unable to build with Conan 2 and C++17

[datalogics-robl]

I'm encountering a problem building innoextract with Conan 2 using the C++17 profile. I get several compile errors, but the first is telling: it's trying to use auto_ptr which is deprecated in C++17. See:

`C:\Users\robl\.conan2\p\b\innoe2f4ac5d724a25\b\src\src\util/unique_ptr.hpp(41): error C2039: 'auto_ptr': is not a member of 'std' (compiling source file C:\

  being compiled (compiling source file C:\Users\robl\.conan2\p\b\innoe2f4ac5d724a25\b\src\src\cli\goggalaxy.cpp)`

I know innoextract can use C++17, I see the flag in the CMakeLists.txt...why would that not be getting picked up?
