What are you trying to compile? How was it configured?

I’m just trying to run code for “Read an image from a file is to include

using ImageType = itk::Image\<PixelType, Dimension\>;

ReaderType::Pointer reader = ReaderType::New();  
const char \* filename = argv[1];

return EXIT\_SUCCESS;

Are there triplets for `vcpkg` on Linux? Which one are you using? Are you using the same options for the example you are building? Maybe you are missing `vcpkg integrate install` or a similar call?

I see that you tried to format the code and the output. Use three backticks (```) for that. See more [here](https://discourse.stonehearth.net/t/discourse-guide-code-formatting/30587).
