Unless you specifies a different CMAKE_INSTALL_PREFIX, then make install will just install the files to your build/sdk directory. (build/bin is populated with regular make.) Try make install without sudo.
In your lib folder, edit astra.toml to look like:
[logging]
# trace, debug, info, warn, error, fatal
level = "trace"
console_output = true
file_output = true
[plugins]
#path = "Plugins"
Then run SimpleDepthViewer-SFML and then post the contents of astra.log here.
