add_global_arguments() can't be used in subprojects. It's
entirely possible that -bad is a subproject but gstreamer
is picked up from an installed location, so we should
really use add_project_arguments() in both cases.
WARNING: Trying to compare values of different types (str, int).
The result of this is undefined and will become a hard error
in a future Meson release.
This patch bumps the required meson to 0.40.1 as gstreamer core just
did, and cleanup some code to use a feature from 0.37 that allow
specifying version range when checking dependency.

We were only ignoring the listed msvc warnings for C language
files and not C++. This was working by the coincidence that we did
not have any instances of these warnings in C++ files. Lately the
build of decklink has been fixed on windows, and it has an
instance of one of these warnings in a C++ file.

If they were not ported after 4+ years it seems unlikely that anybody is
ever going to need them again. They're still in the GIT history if
needed.

a) Use get_pkgconfig_variable() to get the opencv prefix
b) Place an upper limit on the opencv version
c) Ensure that headers are available
(b) and (c) just copy what the configure.ac checks do.
The error is:
unary minus operator applied to unsigned type, result still unsigned
This is a commonly-done operation in gstreamer and it's done on purpose.
It's just noise.
The headers passed as parametter are relative to the build dir
basically "../subproject/gst-plugins-bad/gst-libs/gst/mpegts/XXX.h"
but that does not match what is needed at build time when building as
subproject, also we always add current dir as include_dir so we are
safe including directly.
And link mpegtsdemux against the 'math' library as it is needed.

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded
... and many more. For more details see:

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.
