`WARD`: `WARD` 'Aint Really for Drawing

No-nonsense infinite whiteboard, in the suckless tradition.

This lacks:

multiple types of brushes.
layers.
save/load.
custom palettes
... custom anything, really.
mouse support.

This features:

Rock solid framerate.
Infinite undo/redo.
infinite whiteboard with panning.
Wacom tablet pressure sensitive drawing.
quick minimap view to view the entire whiteboard at a glance.
Not written using web tech: ~800 lines of readable c++ code.
grid background
Draw points with a fixed time lag, then interpolate thickness of the line from 0 to how wide it should be, offset from the time lag.
Take a rolling average both backwards and fowards.

shortcuts:

Q: undo
W: redo
E: toggle E raser
R: R otate to next color.
lower wacom button + drag: pan.
upper wacom button: toggle overview. Tap to move to a location in the overview. Tap upper button in overview mode to quit overview without moving.
Color selection: hover pointer over color in color pot in color palette at bottom row.
Eraser selection: hover pointer over eraser in color palette at bottom left.

The code uses:

the EasyTab library to work with Wacom tablets.
The Milton project as heavy reference on how to work with tablets.
SDL2 for rendering.
Cairo-gl for anti aliased vector graphics.
Spatial hashing to quickly add and delete brush strokes.
Lazy repainting of the entire frame upon change..
Wishes to use FastUIDraw for an even faster backend than cairo.

Instructions for Installation of all dependencies

I am new to this domain of C++ and so the dependencies are quite unfamiliar to me. Could you tell how exactly to install them?

For example, I installed SDL like so: sudo apt install libsdl2-dev libsdl2-2.0-0 -y but I still get the error:

CMake Error at CMakeLists.txt:12 (add_executable):
  Target "ward" links to target "SDL2::SDL2" but the target was not found.
  Perhaps a find_package() call is missing for an IMPORTED target, or an
  ALIAS target is missing?

  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
