Cesium Native: Could NOT find csprng

[Sgambe33]

osgEarth Version (required): 3.7.0

Description of the problem: Could not find csprng while building osgearth with cesium-native support.

What you have tried: I followed the instructions in the documentation literally. Also tried to rebuild cesium-native and osgearth from the beginning.

Screenshot, code block, or data file that will help reproduce the issue:

I can confirm that I see the same problem.

[ELeeScape]

It appears to me that cesium-native doesn't use csprng anymore(?), at least there aren't any references to it in the current cesium-native repo.

[Sgambe33]

So it should be safe to remove it from findCesiumNative.cmake?

[ELeeScape]

Well, probably, but there were two other library problems as well. modp_b64 has changed names to modpbase64 and s2geometry has changed names to s2. Fixing those two allowed the cmake configure to successfully run, but the build fails with a bunch of linker errors that I don't understand yet. I'm pretty sure that no one has tried to (clean) build the Cesium support in osgEarth in quite some time.

Thanks for the PR @ELeeScape . I didn't realize that cesium native moved to using vcpkg as their package manager and removed their git submodules. For now, please use the 0.37 cesium-native release until we have a change to look into this further.

Now, although switching to 0.37 release fixed most of the problems, some still persist and make the install impossible:
