Fixed build error in case of FreeRtos configuration

[psanyi]

Fixed compilation error in CMakeLists.txt due to
incorrectly specified freeRTOS library.

In case of freetos configuration the lv_init() function shall be called
in a task context.

Sorry for the delay. @liamHowatt, @uLipe can you take a look at this PR?

Hi @psanyi, thank you! It builds for me. I'm seeing an issue where it crashes at SDL_Init. Is there a step I'm missing? When I run gdb ./bin/main, I see warning: Corrupted shared library list messages.

If this PR works for anyone else I'm inclined to say let's merge it.

In some cases the stack size for the lvgl task must be increased (depends on lvgl memory usage). Please have a look here:

Aha thanks. We should definitely change that value, either in this PR or another.

Next, I have the exact same problem as @MarcoGit82 here #62 (comment). Do you have this problem too? If so, how do you deal with it? Their solution is to not let LVGL use FreeRTOS internally. Maybe there's an issue with LVGL's FreeRTOS usage.
