include_directories(. ${THREADS_PTHREADS_INCLUDE_DIR}) doesn't seems to be needed, maybe other OS? (tested on Ubuntu 20.04 LTS)

It should not be necessary - I think THREADS_PTHREADS_INCLUDE_DIR does not even exist in CMake anymore. But since you already require cxx_std_11, you could use std::thread and std::mutex instead of pthread in the code. Then there would be no need to find Threads package at all.

Suggestion - make this conditional on if (BUILD_EXAMPLES).

that CMakeLists.txt is included only if BUILD_CV is enabled. Are you sure you want a 2nd condition?

Ideally yes because this is an example. But I see the existing cvdemo does not depend on BUILD_EXAMPLES so it's just a suggestion.
