The target is not available in newer FairMQ versions.

CMakeList.txt files are modified according to modern CMake.
generate_cbm_executable() macro is used to make executable.
Imported targets of each package are used as dependencies.

- Add proper Bmon support to unpack + build digi events chain
- Add proper Much support to unpack + build digi events chain
- Add user parameter + flags to CbmDeviceUnpack to enable/disable the unpacking of each detector
- Add proper handling of disabled detectors in MQ transfer ib both CbmDeviceUnpack and CbmDeviceBuildDigiEvents
- Add parameter to set "MaxNb" type selection in CbmDeviceBuildDigiEvents
- Synchronize unpackers configuration in CbmDeviceUnpack with the one in the current `macro/run/run_unpack_tsa.C`
- Use fles::SubsystemIdentifier instead of hard coded values in CbmDeviceUnpack

Create MQ startup scripts to be installed already at the configuration stage
and store the in the build tree. The difference between the scripts used in
the build tree and the scripts finally installed are the hardcoded directory
information inside. In the scripts to be used inside the build directory this
links to the source and the build directories whereas it links to the
installation directory in case of the scripts which are installed.
Copy the scripts during installation to the correct directory.
Install the MQ executables in the same directory structure as in the build
directory.

- In sim/steer, add CbmSetupStorable class in CbmSetup to convert back and forth from memory Instance to streamable object
- Add support for CbmSetup in MQ parameter server device, with CbmSetupStorable output upon request
- Change CbmSetup usage in MQ Unpack device from Disk access to parameter server request
- Add printout of the received tag in MQ unpack for each detector system

The latest version of our formating rules is applied to all header and source
files as well as to the macros using clang-format 11.0.

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 with FairRoot v18.4.2 on macosx
In FairRoot v18.4.2 some linker settings were removed from the CMake setup.
This breaks the compilation of CbmRoot. Put back the needed seetings for the
linker on macosx in our build system.

Fix NicaFemto installation

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