I have a project using Cesium in C++. I use CesiumGeoreference in C++ to convert location from Unreal to WGS.
It works well with Unreal 4.26 and CesiumPlugin 1.6.
I have updated Unreal to 4.27 and the last version of CesiumPlugin
When i include “CesiumGeoreference.h”, i have this error:
Erreur C2039 ‘optional’ n’est pas membre de ‘std’ … Ellipsoid.h
I have added C++17 support in Build.cs:
CppStandard = CppStandardVersion.Cpp17;
Now i have no error with Ellipsoid.h
But c++17 is not compatible with another external librairie i use in my project.
Is it possible to use Cesium plugin without C++17 ?
