Try running this:

sudo apt-get install mesa-common-dev libglu1-mesa-dev

[arash-arash]

Nothing happened

I try this in the /root/Desktop/Tools and get the same result :

FindOpenGL found both a legacy GL library:

CMake Warning at CMakeLists.txt:51 (find_package):
By not providing "FindSDL2.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "SDL2", but
CMake did not find one.

Could not find a package configuration file provided by "SDL2" with any of
the following names:

SDL2Config.cmake
sdl2-config.cmake

Add the installation prefix of "SDL2" to CMAKE_PREFIX_PATH or set
"SDL2_DIR" to a directory containing one of the above files. If "SDL2"
provides a separate development package or SDK, be sure it has been
installed.

Now you are missing SDL2:

sudo apt-get install libsdl2-dev
