liburing: specifying --prefix to configure script was ineffective, fix. 2019-08-28T17:41:39+00:00 Kevin Vigor kvigor@gmail.com 2019-08-28T16:53:10+00:00 413ee338d46e4f6f2e5c89627b6279b809d4288a The configure script used the default value of the prefix variable (/usr) to determine the includedir etc. *before* parsing the command line to determine if the user specified a prefix. This made configure --prefix ineffective. Fix. Tested with configure --help, configure --prefix, configure --prefix --includedir Signed-off-by: Jens Axboe <axboe@kernel.dk>
