Fixed build problems with latest Boost library versions [DEX-431]

Fixed build problems with latest Boost library versions.
Updated the project to use the minimum C++ standard to be the same as the one required by the Boost library. This means if a user is using an older Boost version we use C++11 but if newer Boost version is used we change level to C++ 14 or C++ 17. the algorithm is like this:

    # Check Boost version and set C++ standard accordingly
    # Our library can not use a lower C++ standard than the one required by Boost.
    if (Boost_VERSION VERSION_LESS 1.70)
        set(CMAKE_CXX_STANDARD 11)
    elseif (Boost_VERSION VERSION_LESS 1.77)
        set(CMAKE_CXX_STANDARD 14)
    else()
        set(CMAKE_CXX_STANDARD 17)  # Boost.JSON, Boost.Process, etc.
    endif()

@ihsandemir Could you add some reasoning about why language level is set to C++14 for Boost [ 1.70, 1.77) ?
According to release notes for Boost 1.82, it is compatible with C++11: https://www.boost.org/releases/1.82.0/

The new baseline requirement for the above libraries, and for most of Boost, will be C++11.

I will re-look at these ranges. I believe the AI replied these ranges since some modules started to support later C++ support with those releases. I also observed our PR builder failed with Boost 1.78.0 wince it tried to use C++ 17 as the compiler. I will double check and fix these versions.
