pqiv configuration

general options:
  --prefix=..           Set the prefix for installed files
  --destdir=..          Set the destdir for installed files (for package
                        maintainers)
  --gtk-version=2       Use GTK+-2.0 even if GTK+-3.0 is available
  --cross=..            Set a cross-compiler prefix (e.g. \`i686-pc-mingw32-')

options to select pqiv's backends:
  --backends=..         Select which backends to include in pqiv
                        (autodetermined by default)
                        Available:
                          libav (Video support, never included by default)
                          gdkpixbuf (images),
                          poppler (PDF),
                          spectre (PS/EPS),
                          wand (ImageMagick, various formats)
  --with[out]-<backend> Alternative syntax for backend selection. Non-specified backends are
                        autodetermined.
  --backends-build=..   Either \`shared' to compile the backends as shared libraries,
                        or \`static' to compile them into pqiv. \`shared' is only of use if you
                        plan to package pqiv and want to get rid of the run-time dependencies,
                        so this defaults to \`static'.
