Erro fatal: GLES2 / gl2.h: Nenhum arquivo ou diretório

Question

Estou tentando instalar o Urho3D no RPi 3. (GPU = 768 MB)

Eu instalei todas as dependências essenciais. Todos os passos correram bem. Até este erro que ocorreu durante o passo final:

[ 56%] Building CXX object Source/Urho3D/CMakeFiles/Urho3D.dir/Graphics/Skybox.cpp.o

Alguma sugestão? O que devo fazer!?

Eu recebi um erro semelhante quando compilei outro projeto. Como o @steeldriver sugeriu, resolvi esse problema instalando a biblioteca:

sudo apt-get install libgles2-mesa-dev
