"Professional CMake" book suggest the following:
"Targets should build successfully with or without compiler support for precompiled headers. It
should be considered an optimization, not a requirement. In particular, do not explicitly include a
precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
generated precompile header on the compiler command line instead. This is more portable across
the major compilers and is likely to be easier to maintain. It will also avoid warnings being
generated from certain code checking tools like iwyu (include what you use)."
Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
The enumeration items are exposed through sub path '.Enum'. When
'ShowAll' is enabled in property view, this sub path is exposed as a
sub property item named 'Enum', and can be either manually edited or
bound with an expression.
Found two memory leaks in class Enumeration
* method tearDown() always ignored to free the memory of the first element
* assignment operator didn't call tearDown() when needed
