IDE DEBUG symbol

[dspverden]

This little change allows crow to be used together with IDEs (like Xcode) that create their own DEBUG symbol during compilation. Else including crow_all.h will make compiling fail because it defines a DEBUG in an enum.

Thank you for your work, but there is already a fix for something similar where the all caps enum is disabled if ERROR is defined, might be best to just add another #ifndef DEBUG there.

I'm referencing the following: https://github.com/CrowCpp/crow/blob/44748e63ea6c12a134191369f10f79402a4be7de/include/crow/logging.h#L16-L22

Actually I think the DEBUG symbol is never used in your code

[The-EDev]

It is meant to be used when defining the logging level by the developer, the examples don't use it because MSVC lacks the all caps definitions.

[dspverden]

Changed it as you suggested.

Just to be 100% certain, it does fix your problem on Xcode, right? (I don't have a mac so I can't test it)

[dspverden]

Yes. This issue prevented me from compiling with Xcode. Now it does compile in Xcode. The reason was that Xcode creates a DEBUG symbol. I could stop Xcode doing this, but then I cannot use DEBUG in the rest of my code.
