[clouds56]

Before reporting an issue please first check the troubleshooting guide. If the issue you're encountering is not solved thereby please state the following in your bugreport:

1. Operating system: Windows 11 x64
2. The way you installed OpenCV: vcpkg install opencv4
3. OpenCV version 4.11.0
4. rustc version (rustc --version) rustc 1.85.0 (4d91de4e4 2025-02-17)
5. Attach the full output of the following command from your project directory:

I see it successfully found build arguments, but seems parse failed. I think shlex cannot handle windows path correctly,

const LINE: &str = r#"C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_highgui4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_ml4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_objdetect4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_photo4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_stitching4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_video4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_videoio4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_imgcodecs4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_calib3d4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_dnn4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_features2d4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_flann4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_imgproc4d.lib  C:\opt\vcpkg\installed\x64-windows\debug\lib\opencv_core4d.lib  kernel32.lib user32.lib gdi32.lib winspool.lib shell32.lib ole32.lib oleaut32.lib uuid.lib comdlg32.lib advapi32.lib"#;
fn main() {
    shlex::Shlex::new(LINE).into_iter().for_each(

}

would output

Maybe we should use winsplit-rs according to https://github.com/comex/rust-shlex/issues/20

Good catch! Thank you for the investigation, I’ll try to provide the fix soon!
