 extra-lib-dirs:
-- upstream/tracy/build
+- upstream/_build/library

+You can use the provided Makefile that will do the thing:
+```sh
+make all # fetch and build stuff
+make test # run the example
+_build/profiler/tracy-profiler & disown # launch the profiler GUI

 This way you can customize configuration.
 Make sure you update package flags to match.
