ENH: Support preprocessor def values in VS6
The add_definitions() command and COMPILE_DEFINITIONS dir/tgt/src properties support preprocessor definitions with values. Previously values were not supported in the VS6 generator even though the native tool supports them. It is only values with spaces that VS6 does not support. This enables support and instead complains only for values with spaces. See issue #8779.
