I am trying to track an object with opencv and publish the center of rectangle to a ROS topic in Rust.
My Cargo.toml looks like this:
[package]
name = "test_package"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
opencv = "0.86.1"
r2r = "0.8.0"
when I cargo build, it fails to build the packages
The error looks like this:
error: failed to run custom build command for `opencv v0.86.1`
Caused by:
process didn't exit successfully: `/home/light/test_package/target/debug/build/opencv-27479df15cc97d32/build-script-build` (exit status: 101)

I am running ubuntu 22.04 LTS with ROS 2 humble.
To reproduce this run these commands :
$cargo new test_packate
$cd test_package
$cargo add r2r
$cargo add opencv
$cargo build
What is the problem here?
I first didn't source ROS, then r2r does not build. After sourcing ROS, opencv does not build. opencv and r2r build properly when I don't depend on both of them. When I depend on only one of them separately it works.
