Description
I've tried configuring ffmpeg with --enable-x11grab and the configure passed without any errors, but x11 input wasn't enabled (I still had the message "Unknown input format: 'x11grab'" after the building process and even ./configure --enable-x11grab .. | grep x11_grab_device didn't produce any output)
Recommendation is that configure should check if needed libraries are installed for x11 input device to be properly built and if they are not installed, to break out of the configure process with a descriptive error message.
I've solved my problem reading this article: http://www.jedi.be/blog/2010/08/30/capturing-the-screen-of-your-virtual-machines-using-x-vnc-rdp-or-native/
which basically says that I lacked some libraries (libx11-dev, libxfixes-dev and libxext-dev), and after installing those, I've had x11_grab_device in the list of input devices.

Can't reproduce the error here, indeed configure --enable-x11grab --enable-gpl will fail with an error message telling which component can't be found, as expected.
Different issue if you enable --enable-indev=x11_grab_device.

Certain optional components like cdio and zlib do not cause a configure error if they were explicitly requested by the user but are unavailable.
