[CMake] Compile flag issues and VS Express

[Yuri Timenkov]

I can assume that 10M stack is reasonable for C code, where it's usual to
allocate temporary buffers on stack (in C++ it's easier to use heap, e.g.
using std::vector).

Bad thing is - impact of this flag is detected only at run time. If with
/Zm your code just won't compile, with /STACK everything compiles and links
perfectly, works fine in simple cases, but you'll receive OOM under load
(in C, when stack will be over).
That's why I didn't insist on changing behavior when found this bug 3 years
ago.
