 Coz has command line options to specify progress points when profiling the application instead of modifying its source. This feature is currently disabled because it did not work particularly well. Adding support for better command line-specified progress points is planned in the near future.

 ## CMake
 When you install coz it installs a cmake config file. To add coz to a cmake project simply use the command `find_package(coz-profiler)`. This will import a target for the library and includes called `coz::coz` and a target for the coz binary `coz::profiler`. For guidance on how to use these targets refer to the CMake documentation.
