[CMake] WIN32_EXECUTABLE property with generator expression

[Petr Kmoch]

Hi Surya.

Generator expressions are not supported universally in CMake; only some
properties support them, and they are all documented as doing so.
WIN32_EXECUTABLE does not support genexes.

As for a workaround, you could create two executable targets, one which
would only be built in Release and one which would be built in other
configurations. Properties such as EXCLUDE_FROM_ALL and
EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG> might come in handy.

However, I find the whole concept somewhat strange. Why is your executable
so fundamentally different between Release and other configurations?
Perhaps there is a different way of achieving your actual goal, without a
need for this.
