It was found that switching form FairSoft jun19p2 to nov20 or apr21 has a
dramatic influence on the performance of the KFParticleFinder. The runtime
for on of the tests increased by roughly a factor 16.

After long investigations it turned out that the compilation flags for the
package were inherited from the ROOT and the CbmRoot project which switched
of the performance flag "-O" when using FairSoft nov20 or apr21.
The merge request fixes the issue by defining the CMAKE_BUILD_TYPE explicitely
to be RelWithDebugInfo.
The merge request also updates the VC version from 1.4.1 to 1.4.2. refs #2220

The new version implements a workaround for CbmRoot. With the latest FairSoft
versions on macosx it comes otherwise to runtime errors when JIT compiling a
macro. The problem is a define statement in termios.h which defines B0 to be 0.
This coonflicts with the parameter B0 used in the header file.

Fix problem with const qualifiers on function return types.

This version is an exact copy of the last revision of the trunk branch
of the old SVN repository of CbmRoor at
https://subversion.gsi.de/cbmsoft/cbmroot/trunk
The old SVN repository will still be available for read access.
