[PATCH 5/5] subsurface-configure.pri: add an extra Marble detection stage

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

On Linux, Marble install in /usr/include and we blindly use it when
building. On Win32 there is no such thing as a marble folder unless
we provide a location for it.

This patch adds an extra Marble detection stage with a pkg-config
target named 'libmarble'.
