This is not actually needed because everything we build is using
@rpath already, and setting it causes dynamic linker path priority
issues with macOS internals causing *all* programs to fail to run
inside gst-env:
```
$ vim
dyld: Symbol not found: __cg_jpeg_resync_to_restart
Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib
Expected in: /Users/nirbheek/projects/repos/gst-build/_build_macos/subprojects/libjpeg-turbo-2.1.0/libJPEG.dylib
in /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib
Abort trap: 6
```
In this case it is caused by libjpeg.dylib, but it can happen with
other dylibs that conflict with dylibs used by macOS internally.

At the point of get_windows_shell() execution, the current directory
equals DEFAULT_BUILDDIR=./build. But cmd_or_ps.ps1 is in SCRIPTDIR=./
(repo root). Point subprocess.check_output() to the correct directory.

The pcfile argument passed to get_target_install_filename() is
guaranteed to be a Path() object so use the .open() method to open the
file instead of the standard open() function.
This makes it possible to run gst-env.py on older systems with pyhton3.5
where the standard open() function cannot handle Path arguments.
The change fixes errors like the following:

Python `set`s have a random ordering. To avoid creating a random
environment, create sorted lists before iterating over them.
Our Rust crates instruct cargo to rebuild if `PKG_CONFIG_PATH` changes,
so this has been causing unnecessary rebuilds.

`bdir[1:]` is supposed to convert `/path/to/bdir` to `path/to/bdir`
which is only correct on UNIX. On Windows it will convert
`C:\path\to\bdir` to `:\path\to\bdir` which is totally wrong.
Use pathlib instead, which makes it trivial to do the conversion using
`joinpath(*bdir.parts)`

This is needed to use gst-uninstalled mode over NFS when gst-build is a
worktree. When this is the case, the .git is a file that links to the original
git tree, but this tree is unlikely to be visible over NFS. Instead of forcing
NFS contorsion, simply ignore the error.
allow for workflows that don't want the gst scripts to start shells,
this can be awkward for higher-level scripts setting up shells
themselves.
this is especially useful in combination with eval, and mimics the sort
of thing you can do with ssh-agent -s.
So gst-build/prefix/etc/xdg/tizonia/tizonia.conf can be found.
Which one contains path to tizonia plugins. Useful when
compiling tizonia-openmax-il and installing it in gst-build
's prefix location:
autoreconf -ifs
./configure --disable-player
--without-libspotify
--prefix=path_to_gst-build/prefix/
make && make install
Allows the following to work:
gst-launch-1.0 videotestsrc ! vp8enc ! omxvp8dec ! xvimagesink
This is the wrong operator to use, which only seems to work because
`os.name` and `'nt'` happen to be the same object. Python 3.8 also
produces a `SyntaxWarning` when encountering this pattern.
On Linux, the library file is stored in the platform triplet directory under the
lib directory (hence for example
lib/x86_64-linux-gnu/gstreamer-1.0/libgstfoo.so) so the regex needs to take this
into account.
With this change the LD_LIBRARY_PATH on Linux now contains only the directories
with gst libs, ignoring the plugins, as initially intended in
c6613d8da2.
Fixes#56
At least in Meson 0.49, the target['install_name'] is a string, not a list, so
the heuristics declared in the is_library_target_and_not_plugin() can't apply
because Python is actually happy to iterate over a string without any warning.
In the case of wine, the env can not be uninstalled, also developers
do not necessiraly care about the fact that it is "uninstalled", the
important thing is that it is a development environment, meaning
that they can work on GStreamer or with GStreamer in the environment.
I still keep the `uninstalled` target to avoid changing people's
habits for now.
