# This class installs just the public headers and a fake pkg-config
|
|
# file which defines the macro "DYNAMIC_JACK". This tells MPD's JACK
|
|
# output plugin to load the libjack64.dll dynamically using
|
|
# LoadLibrary(). This kludge avoids the runtime DLL dependency for
|
|
# users who don't use JACK, but still allows using the system JACK
|
|
# client library.
|
|
#
|
|
# The problem with JACK is that it uses an extremely fragile shared
|
|
# memory protocol to communicate with the daemon. One needs to use
|
|
# daemon and client library from the same build. That's why we don't
|
|
# build libjack statically here; it would probably not be compatible
|
|
# with the user's JACK daemon.
