set(CMAKE_REQUIRED_LIBRARIES backtrace) tells our custom libbacktrace
availability check that it needs to link against libbacktrace.
Seems like it also tells other unrelated compiler-checks like for
-fvisibility=hidden to link against libbacktrace, so if it's not
available they fail as well.
Fixed by unsetting CMAKE_REQUIRED_LIBRARIES after the backtrace check.
While debian-based distros ship libbacktrace as part of libgcc,
apparently in Arch Linux and openSUSE (and possibly others) it's a
separate package, so I mantion it in the README as an (optional)
dependency now and made CMake print a warning if it's not found.
because of https://github.com/microsoft/vcpkg/issues/18098 people shouldn't use vcpkg (at least until they fix that)
libjpeg, libogg and libvorbis(file) aren't needed anymore, so mention that it's only needed for 1.5.1 and older
.. despite the lack of depth-fail ("Carmack's Reverse"), which doesn't really matter for that reason.
I have the impression that some people didn't get this.
"source port" is the usual term for this and what people will probably google for.
mentioning the tested platforms right at beginning might also be helpful for people.
also (hopefully) clarified what EFX/EAX is about, some people who wrote comments
about the release seemed confused about that.
The version will be 1.4.0 because it's not compatible with
Doom3 1.3.1 mod DLLs.
(Note that this commit doesn't mean 1.4.0 is done, I might do some
minor changes before tagging the Release!)
Because Debian Squeeze's libjpeg6 didn't have jpeg_mem_src(), we added
jpeg_memory_src() to provide the functionality.
This shouldn't be needed anymore and without it we can drop libjpeg code
from our repo.
Fixes#110
The implementation is now in framework/minizip/*
instead of framework/Unzip.cpp
This was version 0.15beta, now we use 1.1 from
zlib 1.2.7/contrib/minizip
Some code had to be adjusted for this, but it got
cleaner on the way
