Hi,

I second that answer :)

The way you solved it is factually incorrect as you are including the 
header only UTF files and you declare the dynamic linking variant. Have 
a look at the command line generated for your compiler and your linker, 
you might be linking to the static version while declaring the dynamic 
version with the macro.

Best,
