Re: Help packaging R Quarto Cli

[Sebastien Rey-Coyrehourcq]

Hi,

You're both right, seems there is a flag to skip binary downloading and 
compile the V8 lib.

From the githubpage (https://github.com/denoland/rusty_v8) : "V8 is 
very large and takes a long time to compile. Many users will prefer to 
use a prebuilt version of V8. We publish static libs for every version 
of rusty v8 on Github <https://github.com/denoland/rusty_v8/releases>.

Binaries builds are turned on by default: |cargo build| will initiate a 
download from github to get the static lib. To disable this build using 
the |V8_FROM_SOURCE| environmental variable.

When making changes to rusty_v8 itself, it should be tested by build 
from source. The CI always builds from source"

So, my packaging friend :), what's the best way to push an "export 
V8_FROM_SOURCE=1" or something like that into my rust-deno.scm ?

Best,

SR
