remove unnecessary things from build

[hassanctech]

Issue #, if available:

Description of changes:

• Remove unnecessary dependencies, this SDK does not have a direct dependency on curl, openssl
• Switch to cmake for log4cplus build instead of automake/autoconf, removed automake/autoconf from dependencies
• Remove included CPP Producer header file in the kvssink sample, it was needed only because a simple get time function was being called, instead call the C++ chrono library function directly. This sample is meant to demonstrate usage of kvssink GStreamer element. Client applications using kvssink are not expected to also have a dependency on the C++ Producer library since the kvssink plugin is meant to be loaded at runtime there are no header files from our SDK that need to be included in order to use kvssink GStreamer element.
• Fixes ci issue for mac os clang due to setting LDFLAGS which would choose system curl instead of the one we built
• Bring Windows Log4cplus version up to date with Linux, this required disabling threadpool for Windows since otherwise log4cplus internal threadpool fails to teardown properly
• Explicitly link samples to log4cplus since it includes header files from the logger
