title: Open GL ES - GLM Library and Android Studio
body: <p>I'm trying to import a little C++ Open GL ES framework I wrote for an iOS application into an Android application.
  I want to use Android NDK to import this framework.
  As the framework will be shared between iOS and Android, I placed it outside the jni folder. I specified the path to the source dir of this framework in my grade file as follow (<a href="http://tools.android.com/tech-docs/new-build-system/gradle-experimental#TOC-Source-Set" rel="nofollow noreferrer">http://tools.android.com/tech-docs/new-build-system/gradle-experimental#TOC-Source-Set</a>):</p>
  
  <p><a href="https://i.stack.imgur.com/zaIfT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zaIfT.png" alt="enter image description here"></a></p>
  
  <p>In this framework I used the GLM library for math operation, but as you could see again from the above screenshot, when I try to compile the project I receive the error:</p>
  
  <p>/Users/chicio/Desktop/SpectralBRDFExplorer/SpectralBRDFExplorer/glm/detail/glm.cpp:4:10: fatal error: 'glm/glm.hpp' file not found</p>
  
  <p>What am I doing wrong?</p>
