Qt 5.12: Failed to find "GL/gl.h" in "/usr/include/libdrm"

I have a freshly installed Ubuntu 18.04.3 system (NVIDIA) with only Qt SDK 5.12.5, build-essential, git, and CMake installed. I'm trying to build a Qt project by opening the main CMakeLists.txt in Qt Creator:

Check for working CXX compiler: /usr/bin/g++
Check for working CXX compiler: /usr/bin/g++ -- works

CMake Error at /home/juzzlin/Qt/5.12.5/gcc_64/lib/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake:9 (message):
  Failed to find "GL/gl.h" in "/usr/include/libdrm".
Call Stack (most recent call first):

  /home/juzzlin/Qt/5.12.5/gcc_64/lib/cmake/Qt5Widgets/Qt5WidgetsConfig.cmake:89 (find_package)
  CMakeLists.txt:89 (find_package)

What should I still install?

Note: I haven't installed Qt from repositories at all. Only via the official online installer.

Solution

You need mesa packages.

mesa-common-dev
libglu1-mesa-dev

$ sudo apt install mesa-common-dev libglu1-mesa-dev
And Try.
