I have a rust project that uses the below crate.
reqwest = { version = "0.11.18", features = ["blocking", "json"] }
In order to make it work, I installed "libssl-dev" using the below command in the terminal.
sudo apt install libssl-dev
However, when I tried to run the project using the command cargo run, I got the below error message.
error: failed to run custom build command for `openssl-sys v0.9.90`
Caused by:

This should not happen since openssl is already installed. How do I make it work?
I tried to add the code export OPENSSL_DIR=/usr/include/openssl to the file "/.bashrc" in the home directory but it did not make any difference.
