I used all these flags because I mainly want to play around with the library and having a static, monolithic library with all the features enabled suits that purpose. At first I faced some issues at configuration with GStreamer which wasn't installed but after I installed it the library compiled just fine. For the sake of completeness, these are the exact steps I followed:
#Current dir -> ~/Programs/C++/wxWidgets-3.1.5
mkdir build-gtk
cd build-gtk
../configure #all the above flags
make
sudo checkinstall
and finally I installed the library through the generated .deb file.
I then proceeded to build the sample files with the provided make files. All but two compiled, mediaplayer and splash directories. Again, the exact procedure I followed was:
cd samples
make
The error I got for mediaplayer is:

I've been trying two days now to solve this but I can't figured it out. I've tried installing all the possible GStreamer packages, copying the GStreamer libraries and header files to a bunch of different location, I tried --reinstall and other things but at this point I haven't managed to get anywhere. Does anyone know what am I missing here? How can I compile these sample files?
Edit:
As @VZ. pointed out I should make more clear that:
make files were autogenerated by building wxWidgets library.makefile in the build-gtk/samples directory which would compile in batch all examples.build-gtk/samples/mediaplayer) there was a makefile generated by a bakefile - the first lines are a block comment saying:# =========================================================================
# This makefile was generated by
# Bakefile 0.2.12 ([http://www.bakefile.org][1])
# Do not modify, all changes will be overwritten!
# =========================================================================
make in build-gtk/samples, which compiled all examples except build-gtk/samples/mediaplayer and build-gtk/samples/splash.Following @VZ.'s answer I also tried to manually compile build-gtk/samples/mediaplayer using g++ and changing the order of the libraries I got the following error:
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/libgstvideo-1.0.so: undefined reference to `gst_event_parse_instant_rate_change'

collect2: error: ld returned 1 exit status
Edit 2: I fixed the aforementioned error by running the following:
sudo rm /usr/local/lib/libgstbase-1.0.so*
sudo rm /usr/local/lib/libgstreamer-1.0.*
effectively removing any gstreamer libraries under /usr/local/lib that seemed to be conflicting with some other gstreamer libraries elsewhere in the system.
There is a problem with the order of the libraries in the link command you show, gstreamer libraries must come after -lwx_gtk3u-3.1 and not before it as they do, when using static libraries.
It's not clear to me where does this command actually come from, normally you should run make inside build-gtk/samples/mediaplayer directory, is this really what you're doing? I.e. how exactly do you the provided makefiles and which ones are you using?
This looks like a bug in static monolithic build when using media library and should be fixed in wxWidgets itself. I don't know about the new errors, i.e. the missing gst_event_parse_instant_rate_change and other symbols, I don't have anything like this on my system, so I suspect this might be due to a mix of gstreamer libraries on your system due to your previous attempts to circumvent the problem.
P.S. Avoid using all these --enable-xxx options, they're all on by default anyhow (and those that are off are usually off for a good reason).
