[Development] [Android] Use pkg-config to link with external libraries in qmake project

[Denis Shienkov]

Hi Oswald,

Hmm.. many thanks for your hint, I have modified the
pkg-conf env variables to:

1. PKG_CONFIG_LIBDIR = c:\Android\gstreamer\armv7\lib\pkgconfig
  - a path to all *.pc files.

2. PKG_CONFIG_SYSROOT_DIR = c:\Android\gstreamer\armv7
  - a path to a 'fake' sysroot, which contains an 'include',
    'lib', 'etc' and other directories.

Now, the qmake eats it without warnings...
But, now, it does not detect the gst's include files,
like:

#include <gst/gst.h>

though they are present in:

c:\Android\gstreamer\armv7\include\gstreamer-1.0\gst\

:(
