Fixed msvc 2019 nmake compiler warnings with RTTI.
By default cmake generates cxx_flags with `/GR` parameter.
I updated CMAKE_CXX_FLAGS string and replaced `/GR` -> `/GR-`
How to reproduce:
Visual Studio 2019 x64 command port
mkdir build-msvc2019
cd build-msvc2019
cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_LIBDIR=install ..
nmake
