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.
