Configuration script for the fxengine library.
Usage: $0 [options...]

You should build out-of-tree by creating a build directory and configuring from
there.


Build option:

  --enable-profiling

     By default, profiling is disabled, tht means you will not have access to fps. :(

     This option enables fps count, but you need to have libprof (by Lephenixnoir) installed
