Possible incorrect hardcoded URL for zstd-1.5.6.tar.gz

[crayonstud]

Greetings!

Linux user here (Endeavouros) trying to install agave 3D. It appears that the hardcoded download URL for v1.5.6/zstd-1.5.6.tar.gz is valid but not correct for the expected package download.

The hard-coded URL in the installer (zstd-populate-urlinfo.txt, which is dynamically generated when I run cmake .. - so I can't just manually change the URL) points to: https://github.com/facebook/zstd/archive/v1.5.6.tar.gz

The installer expects an SHA256SUM of 8c29e06cf42aacc1eafc4077ae2ec6c6fcb96a626157e0593d5e82a34fd403c1 but this file's actual SHA256SUM is 30f35f71c1203369dc979ecde0400ffea93c27391bfd2ac5a9715d2173d92ff7.

Now the correct download URL (from Github) appears to be https://github.com/facebook/zstd/releases/download/v1.5.6/zstd-1.5.6.tar.gz. When that file is downloaded and you run SHA256sum on it, you get the expected hash of 8c29e06cf42aacc1eafc4077ae2ec6c6fcb96a626157e0593d5e82a34fd403c1.

Any suggests as to how I can get this installed? Am I missing something?

Any assistance would be greatly appreciated.

If you take a look at: https://github.com/allen-cell-animated/agave/blob/main/renderlib/io/CMakeLists.txt#L35 that's where there's an explicit zstd dependency. I have a new PR which removes this: #195 - maybe try building with that branch?

Thanks for that! I just changed the URL in the proper CMakeList and all is well. Thanks for this cool software too!
