"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
Repurpose DressUp.SupportTransform property to define the following
behavior,
* When disabled (default), only the dressing will be used for patterning.
* When enabled, the additive/subtractive shape of the dressed base
feature will be used for patterning. Any dressing that is not applied
to the based feature will be ignored.
* If the dressing is applied to non-additive/subtractive feature, then
only the dressing will be used for patterning.
New API FreatureAddSub::getAddSubShape() is added to account for the
fact that a dressing (e.g. a fillet) can be either additive or
subtractive, which means that a DressUP feature may contain both
additive and subtractive shapes.
FeatureTransformed is modified to perform both fusion and cut if
required.
