I am writing a GUI interface with C++ and I would like to make the LibRaw processor (i.e. LibRaw Processor = LibRaw();) to be global so that I can use it in any functions and pass it between other forms.
I've tried:

private:
LibRaw Processor1;

it turns out "error C4368: cannot define 'Processor1' as a member of managed 'RAW_GUI::Form1': mixed types are not supported"

And I tried to make it as a pointer:

private:
LibRaw *Processor1;

However I cannot run Processor1 = LibRaw(); as it cannot convert LibRaw * to LibRaw.

Is there any way to make the LibRaw object be global? Or I am thinking in a wrong direction??
