Version 3.7.7 cannot fully build on linux due to missing Steinberg::SystemClipboard::copyTextToClipboard() implementation

Hi,

an attempt to build 3.7.7 for linux results in:

which translates to:

$ c++filt _ZN9Steinberg15SystemClipboard19copyTextToClipboardERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE
Steinberg::SystemClipboard::copyTextToClipboard(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)

Searching this method:

shows, that there's no implementation for it.

Not sure, how to proceed from here (other than implementing it, but I'm a GTK noob).

fixed in VST SDK 3.7.8
