` work fine.
Do you have any suggestions why this symbol is missing, or how to correctly build ITK to use `ImageFileReader` without linker errors?
Thanks in advance!

Are you pointing your project to ITK’s build directory, or an install directory? Using build directory is much more tested. I have a very similar setup, and I don’t remember encountering that error.

This error sounds like a build gone wrong. Can you try clean and rebuild ITK? Does the problem still persist?

Thanks, sir! I’ll try again — really appreciate your help.

Dear Sir,
I ran `cmake --build . --target install` using the install folder because I wanted to get the headers quickly.
If I used the build folder, I would need to include many header files directly from the ITK source, which is quite large. Installing seemed easier to set up the include directories.
However, after doing this, I encountered the linker error I mentioned before.
I also noticed that some ITK documentation for building external projects recommends using CMake to create the project, but I wanted to use Visual Studio 2022 directly instead. I am not sure which folder(s) should be added to the Additional Include Directories.
I apologize if my knowledge is still limited!

If I build my project using CMake, it works correctly.
CMake can find ITK, link all the required modules, and the program runs without errors.
However, when I try to use Visual Studio 2022 directly, I manually add:
- the **install/include** folder to _Additional Include Directories_
- the **install/lib** folder to _Additional Library Directories_
- the ITK **.lib** files to _Input → Additional Dependencies_
When I build my project this way, Visual Studio gives me the linker error I mentioned earlier.
These are all the steps I performed. I think the issue happens because I am not using CMake to build my project.
Thank you for your help, sir.

Take a look at this:

In short, use CMake as meta-build system, and you don’t need to fiddle with include directories. If you don’t want to use CMake for whatever reason, configure some example project using CMake, generate a Visual Studio solution, and then you can copy include directories and link libraries from that example project to your own project.
