Instead of messing with global variables and the like, we introduce two target properties:
- WITH_CXX_EXCEPTIONS: if you want to use C++ exceptions
- WITH_CXX_RTTI: if you need RTTI in your module
You can use the newly introduced set_target_cpp_properties function, with WITH_EXCEPTIONS and WITH_RTTI arguments
We also introduce two libraries :
- cpprt: for C++ runtime routines
- cppstl: for the C++ standard template library
NB: On GCC, this requires to create imported libraries with the related built-in libraries:libsupc++, limingwex, libstdc++
Finally, we manage the relevant flags with the ad-hoc generator expressions
So, if you don't need exceptions, nor RTTI, nor use any runtime at all: you simply have nothing else to do than add your C++ file to your module
Fixes GCC 8 warnings:

There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
