I am modifying the landing module, to make a throw launch module.
While looking at the CMake file there where two lines that caught my attention differing from the example shown in https://dev.px4.io/en/apps/hello_sky.html
STACK_MAIN 1200 # dont understand
COMPILE_FLAGS # dont understand
platforms__common # dont understand
What does the number after STACK_MAIN do, i have seen it at 2000, and now at 1200?
What does COMPILE_FLAGS do?
