I want to compile the viewer with optimizations for my system. I think I have all the necessary prerequisites since I'm also attempting to compile Firestorm. When I run the build script, I get an error when it tries to download the prebuilt openssl from
http://sldev.free.fr/libraries/. The version on that page is openssl-1.0.2t-linux64-20191205.tar.bz2. However, what gets downloaded to the /var/tmp/.../install.cache directory is openssl-1.0.2u-linux64-20200409.tar.bz2, an empty file.
