Use reference in for loop too avoid copying of data.

Add support for C++17
Check for c++ version c++11 or above (11, 14 or 17). With this change it
becomes possible to compile CbmRoot with C++17.

Add missing library.
The FairMQ state machine is now in an extra library which has to be added
for linking when using FairSoft nov20. Test if the library exist and create
the list of dependencies accordingly.

Add missing include directory.
VMC is not any longer included in ROOT but a standealone package, so the
include directory has to be added such that the header files are found.

Add gtest as an optional external package.
With the latest version of FairSoft googletest was removed due to a
recommendation of the gtest developers. Since gtest is no longer part of
FairSoft we have to provide an own version which is compiled as external
project.

Add proper dependency to external gtest project
This dependency is needed to compile the test only if the gtest library is
already available.

Fix compilation error ...

Apply code formatting to all source/header files and root macros.

This version is an exact copy of the last revision of the trunk branch
