GLib 2.62 has deprecated g_memdup(), which is used inline in GStreamer's
gstbytereader.h header. This results in a compilation warning:
In file included from /usr/include/gstreamer-1.0/gst/base/base.h:35,
from ../../src/gstreamer/gstlibcamerasrc.cpp:39:
/usr/include/gstreamer-1.0/gst/base/gstbytereader.h: In function ‘guint8* gst_byte_reader_dup_data_unchecked(GstByteReader*, guint)’:
/usr/include/gstreamer-1.0/gst/base/gstbytereader.h:365:41: error: ‘void* g_memdup(gconstpointer, guint)’ is deprecated: Use 'g_memdup2' instead [-Werror=deprecated-declarations]
365 | return (guint8 *) g_memdup (data, size);
GLib has a mechanism to silence warnings introduced in newer versions,
to allow compilation without warnings on multiple versions of the
library. This is done by setting the GLIB_VERSION_MIN_REQUIRED macro to
the minimum GLib version required.
As we depend on GStreamer >= 1.14, set the minimum GLib version to 2.40.
