Cannot compile on Linux

[GasparPizarro]

First of all, this repo looks awesome. But I cannot compile on Linux, if I go to the example repo and

flutter run -d linux -v

I get

/usr/bin/ld: plugins/flutter_opengl/libflutter_opengl_plugin.so: undefined reference to `eglGetError'

I do have OpenGL , OpenGLES, and OpenCV installed.

Is this the right way to build it though? Would it be possible to compile just the C code?
