I keep getting below error during build at #include <assimp/Importer.hpp>
Error: C1083: Cannot open include file: 'assimp/Importer.hpp': No such file or directory

I have tried to clean the solution, rebuild, updated it with the fullpath, nothing is working.

I have been working and building my OpenGL project in Debug-Win32, I wanted to load models, so came across Assimp. Since they do not release the builds anymore, I downloaded the latest release v5.4.3 from GitHub and followed below to build it locally.

• Open command promt, and run cmake .\CMakeLists.txt
• Once completed, you should be able to see a Assimp.sln
• Open the Assimp.sln and selected Debug and it was available for x64 only
• Once done, copied the generated lib and bin to my project

Project Setup: Visual Studio 2022
Initially I was using Win32, but since I didnt get latest versions of assimp in win32, I reconfigured project to run on x64 as well, added relevant GLEW, GLFW paths and I was able to run application without any issues.

I added the assimp files to my Dependencies. And then added below configurations:

Include Directory Settings (C/C++ -> General -> Additional Include Directories)

src
src\vendor
Core
$(SolutionDir)Dependencies\GLFW\include
$(SolutionDir)Dependencies\GLEW\include
$(SolutionDir)Dependencies\assimp\include

Verified that $(SolutionDir)Dependencies\assimp\include is actually pointing to correct path.

Library Directories & Linking

• Linker -> General -> Additional Library Directories:

$(SolutionDir)Dependencies\GLFW\lib-vc2022
$(SolutionDir)Dependencies\GLEW\lib\Release\x64
$(SolutionDir)Dependencies\assimp\lib\Debug

• Linker -> Input -> Additional Dependencies:

assimp-vc143-mtd.lib
glew32s.lib
glfw3.lib
opengl32.lib
User32.lib
Gdi32.lib
Shell32.lib

Why is Visual Studio not finding assimp/Importer.hpp despite it being in the include directory? Is there something wrong with my configuration?
