+If you see error messages related to OpenGL or GLFW, try building without visualizations

+```bash
+cd 3rdparty/mobile-cv-suite && BUILD_VISUALIZATIONS=OFF ./scripts/build.sh
+cd ../..; mkdir -p target; cd target
+cmake -DBUILD_VISUALIZATIONS=OFF -DUSE_SLAM=ON ..

+```bash
+cd 3rdparty/mobile-cv-suite && WITH_OPENGL=OFF BUILD_VISUALIZATIONS=OFF ./scripts/build.sh
+cd ../..; mkdir -p target; cd target
