Remove the cmake function:
INCLUDE_DIRECTORIES(..)
Replace it by:
TARGET_INCLUDE_DIRECTORIES(...)
It gives us the opportunity to define whether or not OpenAL dependencies
should be exported or not (using PUBLIC or PRIVATE keywoard).
[user visible changes]
The OpenAL PUBLIC headers are exported. When a target depends on OpenAL,
it will have access to its public headers.
Some small refactor along the way.
AL_LOKI_quadriphonic is left alone since that is what the extension is called
and what code expects. All other instances have been fixed for consistency.
Turns out the C version of the cubic resampler is just slightly faster than
even the SSE3 version of the FIR4 resampler. This is likely due to not using a
64KB random-access lookup table along with unaligned loads, both offseting the
gains from SSE.
The default number of auxiliary effect slots is now 64. This can still be
raised by the config file without a hard maximum, but incurs processing cost
for each effect slot generated by the app.
The default number of source sends is now actually 2, as per the EFX docs.
However, it can be raised up to 16 via ALC_MAX_AUXILIARY_SENDS attribute
requests, rather than the previous 4.
Both 5.1 Side and Rear configurations use 'surround51' to look up the
appropriate decoder file. The decoder loader already handles mapping between
rear and side channels, so there's no need for separate options.
Similar to how the library handles it, duplicate entries of the same file are
ignored. This could happen if, for example, XDG_DATA_DIRS contains the same
path multiple times.
CMake 2.8.5 added the GNUInstallDirs module, which provides various
variables following the CMAKE_INSTALL_*DIR pattern to allow users a more
flexible installation setup and to provide sensible defaults while
respecting distribution specific install locations like lib64 for RPM
based linux distributions or debian multiarch tuples.
