The current situation of the Gstreamer detection does not always honor
all the configurations set by the user, among this:
- if both WITH_GSTREAMER and WITH_GSTREAMER_0_10 are off, but
Gstreamer 0.10 is installed in the system, Gstreamer 0.10 support will
be enable;
- if both WITH_GSTREAMER and WITH_GSTREAMER_0_10 are on, only checks for
Gstreamer 0.10 will be run.
This patch fixes the Gstreamer detection like this:
| -DWITH_... | Package installed || OpenCV |
| GSTREAMER | GSTREAMER_0_10 | gst-1.x | gst-0.10 || gst. support |
+===========+================+=========+==========##==============+
| OFF | OFF | - | - || none |
| OFF | ON | - | no || none |
| OFF | ON | - | yes || gst-0.10 |
| ON | OFF | no | no || none |
| ON | OFF | no | yes || gst-0.10 |
| ON | OFF | yes | - || gst-1.x |
| ON | ON | yes | - || gst-1.x |

* There's no OPENCV_BINARY_DIR variable;
* No need to append CMakeFiles/CMakeTmp, as CMake does it for you;
* Output variables are unused;
* Wrong usage of CMAKE_FLAGS;
* Small quoting and style issues.
Now the HAVE_* macros are set using cvconfig.h. Previously most
of them already were there, but were always undefined. One,
HAVE_COCOA, I had to add.
This also makes the CMake code more consistent; now, WITH_* variables
are always checked in cmake/*, while HAVE_* variables are checked in
modules/highgui/CMakeLists.txt.
The video(4) driver provides a Video4Linux2 compatible API for
various video peripherals. This patch propagates HAVE_VIDEOIO if
the sys/videoio.h include file is found, which is the signature of
video(4).
