I follow the developer instructions to build the Cesium for Unity package, but when I get to the step where you need to compile the native~ library, I get these errors:
D:/myunity/cesium-unity-samples/Packages/com.cesium.unity/native~/extern/cesium-native/extern/s2geometry/src/s2/util/endian/endian.h:111:2: error: #error “Unsupported bytesex: Either IS_BIG_ENDIAN or IS_LITTLE_ENDIAN must be defined”
#error “Unsupported bytesex: Either IS_BIG_ENDIAN or IS_LITTLE_ENDIAN must be defined” // NOLINT

I am using dotnet SDK version 7.0.306
I am using GCC 7.3.0
I am using windows 11 Home Edition
I am using CMake 3.27.0
Is there anything I’m doing wrong? How can I fix this?
