With this cmake variable set to
ON, the flameshot capture GUI window won't bypass the
window manager. This allows you to manipulate the capture GUI window like any
other window while debugging.
This can be useful if a debugging breakpoint is triggered while flameshot is in full screen mode. Without this variable, you might have trouble inspecting the code due to a frozen full-screen window.
cmake -DFLAMESHOT_DEBUG_CAPTURE=ON ...
