with BSD make and to make use of cmake in 'distcheck' target
conditional on if cmake is available.

CMake reads all version information directly from configure.ac to
avoid duplication of values. This basically greps over the file
for the LIBTIFF_* variables, then translates them to the form
needed for cmake. This includes the release version and libtool
shared library version information.
Make shared/static library building configurable. Currently it
always builds shared libraries, with static libs having a _static
suffix (copying zlib, but it means it's got a non-standard name).
CMake has a -DBUILD_SHARED_LIBS=ON|OFF option to select one or the
other, which is now used instead. There's now a single "tiff"
target to build either shared or static as required, and all the
tests and tools are linked with this. Note: the Windows tests fail
when linked with a static libtiff (says: libtiff.dll not found).
Not really a regression since this was not tested up to this
point, and it's likely the unit tests haven't (ever?) been run on
Windows with a static libtiff, so there's some additional
portability issue here to address. Works fine on UNIX systems,
and fine on Windows with the default to build a DLL.
Add a missing file which wasn't being distributed, causing unit
tests to fail. Note that "find . -name '*.cmake'" lists all the
CMake files which need distributing in addition to all the
CMakeLists.txt files (which now are distributed).
libtiff mailing list on Mon, 22 Jun 2015 21:21:01 +0100. Several
corrections to ensure that the autotools build still works were
added by me. I have not yet tested the build using 'cmake' or
MSVC with 'nmake'.
add-on library.
* test/Makefile.am (JPEG_DEPENDENT_CHECK_PROG): raw_decode
requires JPEG support to compile. Use Automake conditional to
only include it when JPEG support is available.
some TIFF/FX support in libtiff. Add the tag definitions to
tiff.h. Add the related TIFF field definitions to tif_dirinfo.c,
and also fixes an error in a comment. Adds the photometric values
to tif_print.c, and fixes a bug. These changes are by Steve
Underwood.
* libtiff/tif_write.c: Fix bug rewriting image tiles in a
IJG JPEG 7+ uses a different upsampling algorithm which produces
different numeric results.
* libtiff/tif_jpeg.c (JPEGPreDecode): Patch from Even Rouault to
work with IJG JPEG 7+.
The test case was ignoring the documented API for TIFFReadRGBATile,
namely that the output pixels are uint32's and the macros TIFFGetR etc
should be used to fetch the pixel components.
Original patch by Marcus Meissner, somewhat cleaned up by me.
ELF systems with the GNU linker. Support is enabled via
--enable-ld-version-script. Disabled by default for now until
there is a decision for how to deploy a libtiff with versioned
symbols after libtiff 4.0.0 was already released.
the run-time target whereas target is used to specify the final
output target if the package is a build tool (like a compiler),
which libtiff is not. Resolves libtiff bug 2307 "Use
AC_CANONICAL_HOST macro".
* libtiff/tif_fax3.c (Fax3SetupState): Avoid under-allocation of
buffer due to integer overflow in TIFFroundup() and several other
potential overflows. In conjunction with the fix to TIFFhowmany(),
fixes CVE-2010-1411.
* libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would
result in an integer overflow. This causes TIFFroundup() to also
return zero if there would be an integer overflow.
Nolde. Major updates to add significant functionality for reading
and writing tile based images with bit depths not a multiple of 8
which cannot be handled by tiffcp.
