Using CMakePackageConfigHelpers, we can generate a relocatable
OpenJPEGConfig.config, using the PATH_VARS feature to make
CMAKE_INSTALL_LIBDIR relative to the installed location.
This change is needed for me when cross-compiling since
CMAKE_INSTALL_FULL_LIBDIR is a path inside the sysroot rather than
an absolute path to the actual includes. Without this change poppler
ends up passing a -I flag that does not exist.
This includes fallback code for CMake 2.8, which adds a bit of complexity,
since I'm not sure if raising the minimum to 3.0 (now over 8 years old)
is acceptable.
* Add GNUInstallDirs for standard installation directories
Distributions are given standard variables for already existing hooks.
Multiarch libdirs is taken care of automagically.
Raises minimum cmake version by a little.
* Handle CMAKE_INSTALL_xxx being absolute paths for .pc file generation
In some cases the CMAKE_INSTAL_{BIN,MAN,DOC,LIB,INCLUDE}DIR variables
may turn out to be absolute paths in which case prepending ${prefix} in
the pkg-config .pc files will result in incorrect values.
For .pc file generation, figure out if these variables are absolute and
omit the prefix in the configured file when so.

allows for the usage of $(pkgconf --static --cflags libopenjp2) to produce
the proper CFLAGS for static linking. Relies on pkgconf rather than pkg-config
Add a -allow-partial option to opj_decompress utility and a opj_decoder_set_strict_mode() option to the API

and add a -GuardBits option to opj_compress.
The recently-released SMPTE DCP Bv2.1 Application Profile (link below)
says that the number of guard bits in the QCD marker shall be 1 for 2K
content and 2 for 4K content. This change allows the number of guard bits
to be configured, so that users of openjpeg have the control they need to meet the specification.

This is an alternative implementation of https://github.com/uclouvain/openjpeg/pull/1388
that keeps ABI unchanged.
As discussed in pull request 1396, added a check for integer overflow.
Change list:
Defined num_images as unsigned int
Moved the if statement to check for an empty directory to the beginning of the read directory section
Added a check to see if num images would roll back to zero when incrementing.
Sometimes, given the same (16-bit TIF) input, one wants to generate a variety of J2C outputs (say, 16-, 12-, and 10-bit). This patch allows one to downsample input files, and so makes it easier to automate OpenJPEG in mass generation of J2Cs without having to pipe though an image processing program.
