i compiled the solution and i expected it to work without error but it did not
I am trying to compile a project using ImGui however I get these errors:

This is really quite odd because the files USED to be inside a folder called src\vendor but are now in another folder called Dependencies\imgui. It doesn't make sense to me why it is even mentioning a folder called vendor at all? Here are my search directories for #include
$(SolutionDir)Dependencies\imgui
$(SolutionDir)Dependencies\GLEW\include
$(SolutionDir)Dependencies\SDL2\include
There is a preprocessor for GLEW but not IMGUI, and there are linker settings for GLEW AND SDL2 but not IMGUI. These are compile errors. What could be the problem?
I have a problem with creating new c++ classes. For example, a did a Player controller and it compiles but when it is open in Visual Studio, it says there are too many errors for the IntelliSense to function properly. My Unreal Engine version is 4.25 and visual studio 2019 version 16.6.2
Then it gets crazy in the Error List with 15390 errors

Go to a VS solution folder. Delete following folders : ".vs", "Intermediate", "Saved"
Delete solution (*.sln file). Keep *.uproject
Right click on *.uproject in explorer, click "switch unreal engine versoin" and select your current engine version. Project files and solutions will get regenerated.
Open your vs solution. Your generated files will be missing, so hit "build" button.
Go to Tools->Options->Text editor->Advanced, set "Recreate Database" to "true" and restart visual studio
Wait and pray for it to work (worked for me tho)
I have something like this nearly daily. My advice is not to rely on IntelliSense when it comes to errors and change the "Errors" window in Visual Studio to just display "Build only" errors.
When you build, you'll only get the real errors that are actually messing up your build. Because the UnrealHeaderTool actually creates a lot of code in the background, some things are not available when creating a new class or refactoring methods.
A best practice seems to be to just rely on what MSBuild gives you, instead of waiting for IntelliSense to catch up. Fixing an error like "could not find this file" or "undefined type" from the compiler should be way easier than trying to tell IntelliSense to understand that there exist macros that are not Preprocessor-macros, but UHT macros.
If you just stick to the Build errors, the problem will go away at some point. At least for me it did.
Also note that the unity build that Unreal uses, may break files you did not even work on, because you forgot an include that was already there when the build tool merged the files in the last build.
I followed this video tutorial for installing OpenCV for Visual C++ in Visual Studio 2015 (14) under Windows 10. https://www.youtube.com/watch?v=7SM5OD2pZKY
However I get this error:

Please suggest solution.
I am trying to build ClamAV and am running into Linker errors. I tried doing what was said here in the answer: OpenSSL errors - ClamAV build on Windows 10 for the Linker part, however, I don't see any Linker option in Visual Studio 2010.
This is what the project properties look like:
There is nothing in Common Properties either. These are the errors I'm getting:

Would anyone have any idea on how I can fix this? Any help would be appreciated, thanks!
