Hi,
I’ve started a small project, and all was going well until I did:
cargo add reqwest
Then rust complained about pkg-config or openssl or libssl-dev, I’m not sure. Here is what is says:
[...]
Compiling openssl-sys v0.9.77
error: failed to run custom build command for `openssl-sys v0.9.77`
Caused by:
process didn't exit successfully: `/home/runner/reqwest-test/target/debug/build/openssl-sys-a80daff917dc506e/build-script-main` (exit status: 101)

thread 'main' panicked at '
Could not find directory of OpenSSL installation, and this `-sys` crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it, you can set the `OPENSSL_DIR` environment variable for the
compilation process.
Make sure you also have the development packages of openssl installed.
For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.
If you're in a situation where you think the directory *should* be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl
and include information about your system as well as this message.
$HOST = x86_64-unknown-linux-gnu
$TARGET = x86_64-unknown-linux-gnu
openssl-sys = 0.9.77
It looks like you're compiling on Linux and also targeting Linux. Currently this
requires the `pkg-config` utility to find OpenSSL but unfortunately `pkg-config`
could not be found. If you have OpenSSL installed you can likely fix this by
installing `pkg-config`.

This can be reproduced by starting a new Rust project, and simply adding reqwest and trying to run the hello wolrd code again. See this replit: https://replit.com/@Pierric82/reqwest-test
Any idea how to fix this? Reqwest is a fairly common crate, and I do need to use retrieve some JSON from remote URLs.
Thanks!
Pierric.
