compiling on raspberry pi3 fails on ofxImGui/src/EngineOpenGLES.cpp

[danbz]

in the config it states

'linuxarmv6l:
#TODO needs EngineGLFW.cpp exclude "

however EngineGLFW.cpp appears to compile but appears to fail compiling
ofxImGui/src/EngineOpenGLES.cpp

/home/pi/openFrameworks/addons/ofxImGui/src/EngineOpenGLES.cpp: In member function ‘virtual bool ofxImGui::EngineOpenGLES::createDeviceObjects()’:

Just rename g_UniformLocationPosition into g_AttribLocationPosition in /home/pi/openFrameworks/addons/ofxImGui/src/EngineOpenGLES.cpp:130:3
