Before this commit the MacOS packaging script failed on copying Codecs
if the respective directory already existed (e.g. because the packaging
script has been run before).
Furthermore the script called a function to delete a directory (tree)
on a file. This error never surfaced before because usually when this
script is run, the respective file doesn't exist yet.
Both issues are fixed by this commit. It is now possible to run the
packaging script multiple times consecutively without it erroring on
already existing files.
Our qmake project forcibly put binaries into the "release" folder, inside the repository.
With the CMake project this is not the case: the source and binary directories can even reside on different drives.
Unfortunately the binary directory was hardcoded in both "build-overlay-installer" and "osxdist.py".
As for the source directory, both scripts simply expected to be run from the repository's root.
This commit adds the "--source-dir" and "--binary-dir" options to "osxdist.py". Default values: "." and "build", respectively.
"build-overlay-installer" now expects its working directory to be the binary folder.
No options are added; they are not required because the script is executed by "osxdist.py", which takes care of setting the working directory.
Extra change: "build-overlay-installer" now uses "PlistBuddy" rather than "defaults", because the latter doesn't support reading from a file anymore in macOS Catalina (10.15).
CELT 0.11.0 provides better quality in comparison to CELT 0.7.0, but the two versions of the codecs are not compatible, which is why we provided both of them.
Opus was introduced in Mumble 1.2.4 (7586a61226), thus we expect that most (if not all) users are using it.
By removing CELT 0.11.0 we don't break backwards compatibility, because it's provided by CELT 0.7.0.
The main reason for removing the codec is the fact that its discontinued (in favor of Opus).
Also, CELT 0.11.0 was removed from the Debian package back in 2012: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=682010
QMake always passes "-arch x86_64" after the parameters specified in our project file, meaning that we can't build the application as 32 bit.
This option allows us to disable the feature (warning when trying to run Mumble on a 32 bit system) for the CI build.
The script copies the CELT (dynamic) libraries into the App Bundle, so that they are installed and then loaded by Mumble.
This commit adds the Opus library to the list of files to copy, necessary because it is loaded at runtime since e0ee016e5c.
We used to use DIST for referencing extra files that should be included
in our tarballs created by 'make dist'.
However, we've since migrated away relying on 'make dist' in release.pl.
Instead, we include everything, and have a list of items to exclude, such
as IETF RFC drafts distributed in 3rdparty/speex-src that do not adhere to
the Debian Free Software Guidelines.
