"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
This adds "SingleSolidRuleMode" enum that controls if PartDesign will
enforce singular solid. By default the single-solid is enforced so
nothing changes for the user, it must be explicitly disabled by setting
new Allow Compound boolean property on a given body.
Default for this value is controled using user parameter under
Mod/PartDesign/AllowCompoundDefault
This reverts commit 92db97a26dbdd5c2210df39dd08a716faf6102f6.
There is no need to make this a static property because it can be added at runtime via Python or the GUI
