I find this to be wrong. Usually when you give the macro the argument, 
you know what you are expecting. So default arguments should come later.

I was thinking earlier, isn't it possible to make a general macro to 
handle this ?
Usually the steps to check for a library are always the same.
- Check for package config on non win32.
- Search for the includes
- Search the binary
Quite always the same steps.

I'll try to remove the one I found then.
