13 # This makes the presumption that you are include al.h like
17 # The reason for this is that the latter is not entirely portable.
18 # Windows/Creative Labs does not by default put their headers in AL/ and
19 # OS X uses the convention <OpenAL/al.h>.
21 # For Windows, Creative Labs seems to have added a registry key for their
22 # OpenAL 1.1 installer. I have added that key to the list of search paths,
23 # however, the key looks like it could be a little fragile depending on
24 # if they decide to change the 1.00.0000 number for bug fix releases.
25 # Also, they seem to have laid down groundwork for multiple library platforms
26 # which puts the library in an extra subdirectory. Currently there is only
27 # Win32 and I have hardcoded that here. This may need to be adjusted as
28 # platforms are introduced.
29 # The OpenAL 1.0 installer doesn't seem to have a useful key I can use.
30 # I do not know if the Nvidia OpenAL SDK has a registry key.
32 # For OS X, remember that OpenAL was added by Apple in 10.4 (Tiger).
33 # To support the framework, I originally wrote special framework detection
34 # code in this module which I have now removed with CMake's introduction
35 # of native support for frameworks.
36 # In addition, OpenAL is open source, and it is possible to compile on Panther.
37 # Furthermore, due to bugs in the initial OpenAL release, and the
38 # transition to OpenAL 1.1, it is common to need to override the built-in
40 # Per my request, CMake should search for frameworks first in
41 # the following order:
42 # ~/Library/Frameworks/OpenAL.framework/Headers
43 # /Library/Frameworks/OpenAL.framework/Headers
44 # /System/Library/Frameworks/OpenAL.framework/Headers
46 # On OS X, this will prefer the Framework version (if found) over others.
47 # People will have to manually change the cache values of
48 # OPENAL_LIBRARY to override this selection or set the CMake environment
49 # CMAKE_INCLUDE_PATH to modify the search paths.
