configure: cuda_llvm: fix include path for MSYS2

pseudo-windows paths on execution time.
Since there was no space between '-include' and the path, MSYS2 doesn't
detect the path properly.

-This muxer computes and prints a cryptographic hash of all the input frames,

-to do a complete binary comparison.
-
-By default audio frames are converted to signed 16-bit raw audio and
-video frames to raw video before computing the hash, but the output
-of explicit conversions to other codecs can also be used. Timestamps

-but supports several other algorithms.
-
-The output of the muxer consists of one line per stream of the form:
-@var{streamindex},@var{streamtype},@var{algo}=@var{hash}, where
-@var{streamindex} is the index of the mapped stream, @var{streamtype} is a

 A description of the currently available protocols follows.
 
-@section amqp
-
-Advanced Message Queueing Protocol (AMQP) version 0-9-1 is a broker based
-publish-subscribe communication protocol.
-
-FFmpeg must be compiled with --enable-librabbitmq to support AMQP. A separate
-AMQP broker must also be run. An example open-source AMQP broker is RabbitMQ.
-
-After starting the broker, an FFmpeg client may stream data to the broker using
-the command:
-
-@example
-ffmpeg -re -i input -f mpegts amqp://[[user]:[password]@@]hostname[:port]
-@end example
-
-Where hostname and port (default is 5672) is the address of the broker. The
-client may also set a user/password for authentication. The default for both
-fields is "guest".
-
-Muliple subscribers may stream from the broker using the command:
-@example
-ffplay amqp://[[user]:[password]@@]hostname[:port]
-@end example
-
-In RabbitMQ all data published to the broker flows through a specific exchange,
-and each subscribing client has an assigned queue/buffer. When a packet arrives
-at an exchange, it may be copied to a client's queue depending on the exchange
-and routing_key fields.
-
-The following options are supported:
-
-@table @option
-
-@item exchange
-Sets the exchange to use on the broker. RabbitMQ has several predefined
-exchanges: "amq.direct" is the default exchange, where the publisher and
-subscriber must have a matching routing_key; "amq.fanout" is the same as a
-broadcast operation (i.e. the data is forwarded to all queues on the fanout
-exchange independent of the routing_key); and "amq.topic" is similar to
-"amq.direct", but allows for more complex pattern matching (refer to the RabbitMQ
-documentation).
-
-@item routing_key
-Sets the routing key. The default value is "amqp". The routing key is used on
-the "amq.direct" and "amq.topic" exchanges to decide whether packets are written
-to the queue of a subscriber.
-
-@item pkt_size
-Maximum size of each packet sent/received to the broker. Default is 131072.
-Minimum is 4096 and max is any large value (representable by an int). When
-receiving packets, this sets an internal buffer size in FFmpeg. It should be
-equal to or greater than the size of the published packets to the broker. Otherwise
-the received message may be truncated causing decoding errors.
-
-@item connection_timeout
-The timeout in seconds during the initial connection to the broker. The
-default value is rw_timeout, or 5 seconds if rw_timeout is not set.

-@section zmq
-
-ZeroMQ asynchronous messaging using the libzmq library.
-
-This library supports unicast streaming to multiple clients without relying on
-an external server.
-
-The required syntax for streaming or connecting to a stream is:
-@example
-zmq:tcp://ip-address:port
-@end example
-
-Example:
-Create a localhost stream on port 5555:
-@example
-ffmpeg -re -i input -f mpegts zmq:tcp://127.0.0.1:5555
-@end example
-
-Multiple clients may connect to the stream using:
-@example
-ffplay zmq:tcp://127.0.0.1:5555
-@end example
-
-Streaming to multiple clients is implemented using a ZeroMQ Pub-Sub pattern.
-The server side binds to a port and publishes data. Clients connect to the
-server (via IP address/port) and subscribe to the stream. The order in which
-the server and client start generally does not matter.
-
-ffmpeg must be compiled with the --enable-libzmq option to support
-this protocol.
-
-Options can be set on the @command{ffmpeg}/@command{ffplay} command
-line. The following options are supported:
-
-@table @option
-
-@item pkt_size
-Forces the maximum packet size for sending/receiving data. The default value is
-131,072 bytes. On the server side, this sets the maximum size of sent packets
-via ZeroMQ. On the clients, it sets an internal buffer size for receiving
-packets. Note that pkt_size on the clients should be equal to or greater than
-pkt_size on the server. Otherwise the received message may be truncated causing
-decoding errors.
