Bug#949846: libpyside2-dev: Wrong include path for CMake in INTERFACE_INCLUDE_DIRECTORIES

[Tobias Ellinghaus <t_ellinghaus@gmx.de>]

Hi,

libshiboken2-dev 5.15.0-1 is now in sid, and it seems this is broken again.
The packages from experimental used to work fine, but they are gone now.

It would be great if someone could have a look.

Thanks in advance
Tobias
