SHA256SUMS failed

[gmnail]

I get wrong when I build the cesium-o3de-sample, as I see in the cmakelist:

but the External/Packages dir of my cesium-o3de have nothing named Install/SHA256SUMS how can I get this?

[baothientran]

the directory is created once you build cesium-native and other third party in External directory. You can find the instruction for building the plugin in this doc https://github.com/CesiumGS/cesium-o3de/blob/main/Documentation/developer-setup.md.

It would also be possible instead to add the folder containing the package, once its built, (well, its FindCesium file) to the CMAKE_MODULE_PATH variable (append to the beginning). Then call find_package(CesiumNative MODULE REQUIRED) to bring it in, without having to engage the package zip or unzip utility at all. Which can simplify iteration workflows.
