Troubleshooting

CMake / Build process

Error: Failed to find "GL/gl.h" in "/usr/include/libdrm"

libgl is a Qt dependency. This error can be fixed by installing libgl-dev on Linux (e.g., on Debian-based systems using apt-get install libgl-dev). Install it, then remove and recreate the build directory and continue the build process by executing cmake .. inside the build folder.
