I am getting error about X11 library

when I run cmake build I get this error:

CMake Error at cmake/Macros.cmake:296 (message):
  Missing item in X11_X11_LIB;X11_Xrandr_LIB
Call Stack (most recent call first):
  src/SFML/Window/CMakeLists.txt:239 (sfml_find_package)

I have already installed x11 library and I have even added /usr/lib path to FindX11.cmake. Btw I am using Ubuntu 20.04, and this whole concept with cmake is still pretty new for me, so when possible give me as detailed instructions as possible.


Solution 1:

You have to install related development packages by

sudo apt-get update
sudo apt-get install libx11-dev libxrandr-dev
