#
# This configure script is *not* autoconf-based and has different semantics.
# It attempts to autodetect all settings and options where possible. It is
# possible to override autodetection with the --enable-option/--disable-option
# command line parameters.  --enable-option forces the option on skipping
# autodetection. Yes, this means that compilation may fail and yes, this is not
# how autoconf-based configure scripts behave.
#
# configure generates a series of configuration files:
#  - config.h contains #defines that are used in the C code.
#  - config.mak is included from the Makefiles.
#
# If you want to add a new check for $feature, look at the existing checks
# and try to use helper functions where you can.
#
# Furthermore you need to add the variable _feature to the list of default
# settings and set it to one of yes/no/auto. Also add appropriate
# --enable-feature/--disable-feature command line options.
# The results of the check should be written to config.h and config.mak
# at the end of this script. The variable names used for this should be
# uniform, i.e. if the option is named 'feature':
#
# _feature     : should have a value of yes/no/auto
# def_feature  : '#define ... 1' or '#undef ...' for conditional compilation
# _ld_feature  : '-L/path/dir -lfeature' GCC options

  --extra-libs=FLAGS          extra linker flags
  --extra-libs-mpv=FLAGS      extra linker flags for mpv

This configure script is NOT autoconf-based, even though its output is similar.
It will try to autodetect all configuration options. If you --enable an option
it will be forcefully turned on, skipping autodetection. This can break
compilation, so you need to know what you are doing.

Check $TMPLOG if you wonder why an autodetection failed (make sure
development headers/packages are installed).

NOTE: The --enable-* parameters unconditionally force options on, completely
skipping autodetection. This behavior is unlike what you may be used to from
autoconf-based configure scripts that can decide to override you. This greater
level of control comes at a price. You may have to provide the correct compiler
and linker flags yourself.
If you used one of these options and experience a compilation or
linking failure, make sure you have passed the necessary compiler/linker flags
to configure.
