Unfortunately the extension makes use of dynamically loaded libraries which nix cannot accomodate out-of-the-box. Fortunately there's a simple solution in the use of [https://github.com/Mic92/nix-ld nix-ld]. Here's a simple flake.nix to get you started (I'll focus on the devShell part for brevity): | Unfortunately the extension makes use of dynamically loaded libraries which nix cannot accomodate out-of-the-box.

The important lines are the two lines starting with "NIX_LD...". They will let nix-ld wrap the required, dynamically loaded libraries so that they are found when building the devShell. | The important lines are the two lines starting with "NIX_LD...".
