Build error while compiling vst3sdk on Fedora 40

[ycollet]

I am trying to build vst3sdk on Fedora 40 beta and I met the following error during compilation:

In file included from /builddir/build/BUILD/vst3sdk/vstgui4/vstgui/lib/cframe.cpp:7:
/builddir/build/BUILD/vst3sdk/vstgui4/vstgui/lib/finally.h: In constructor ‘VSTGUI::FinalAction<Proc>::FinalAction(VSTGUI::FinalAction<Proc>&&)’:
/builddir/build/BUILD/vst3sdk/vstgui4/vstgui/lib/finally.h:21:30: error: expression cannot be used as a function
   21 |                 other.invoke (false);
      |                 ~~~~~~~~~~~~~^~~~~~~

Replaced:

other.invoke (false);

By:

other.invoke = false;

And now it builds ....

[ycollet]

And it finally hangs with a missing symbol ....
