Demo for RRethy/vim-illuminate#204
Inside cloned directory run:
cmake -B build -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -G Ninja
ln -s ./build/compile_commands.json .
problem is visible with function region. When you place cursor on definition pressing 'n' works only once and switches to usage. Pressing 'p' continuously switches between definition and usage.
