title: Can't find assimp header files
body: <p>I'm using CMake and I have a number of external libraries I'm using. </p>
  
  <p>Under a folder </p>
  
  <pre><code>`ext/
   - eigen
   - glm
   - glfw
  `
  </code></pre>
  
  <p>All of this compiles fine and I can run my code properly. However, I installed assimp by cloning a repo into <code>ext/</code> and I updated my CMakeLists.txt to be</p>
  
  <pre><code>### Add src to the include directories
  include_directories("${CMAKE_CURRENT_SOURCE_DIR}/src")
  
  ### Include Eigen for linear algebra
  include_directories("${CMAKE_CURRENT_SOURCE_DIR}/ext/eigen")
  
  ### Include glm for other math
  include_directories("${CMAKE_CURRENT_SOURCE_DIR}/ext/glm")
  
  include_directories("${CMAKE_CURRENT_SOURCE_DIR}/ext/assimp") # new line
  </code></pre>
  
  <p>And when I go to my main and write</p>
  
  <pre><code>#include &lt;assimp/Importer.hpp&gt;
  </code></pre>
  
  <p>VSCode doesn't complain. However, when I compile it I get </p>
  
  <p>"fatal error: 'assimp/Importer.hpp' file not found"</p>
  
  <p>What am I doing wrong?</p>
