40ece64ff7 added 32-bit support 
issues remaining:

- params for compression ratio, chrominance subsampling, etc. ...  imagemagick
  jp2 files are half the size of ours https://imagemagick.org/script/jp2.php

- metadata, eg. icc profile etc.

- alpha channels do not seem to be tagged correctly

- tests

fae5d9cc82 improve configure summary table 
- order and group summary
- list by file format type, rather than library
- describe as load/save rather than import/export
- also --vips-config output

I split the VIPS_CFLAGS, VIPS_INCLUDES and VIPS_LIBS var settings into
the various finders for maintainability.
