Missing createsamples utility after building from source opencv 4.0.0 [closed]

edit

I check in the directory opencv/build/bin directory and can the see other utilities there, but can't find opencv_createsamples.

I don't know if this is related but I noticed the CMakeLists.txt in the opencv/apps/ directory have commented out the lines:

# ocv_add_app(traincascade)
# ocv_add_app(createsamples)

I am running an Ubuntu 18.04.1 LTS version

Thank you in advance.
