2015.08.29 11:34 "[Tiff] [patch] Docs for cmake build and some minor tweaks", by Roger Leigh

Adds documentation to build.html for building with CMake.

- Adds cmake section, copied from the autoconf/UNIX build section

May need a bit of proofreading; it's the first plain HTML I've edited since 1999!

It also adds a couple of tweaks:

- adds ld-version-script option to cmake build to match autoconf
   (note: defaults to on to be ABI-compatible by default with all Linux

distribution builds; worth also switching the autoconf default to ON to match the distributions as well since it's disabled if unavailable?) Otherwise builds aginst custom libtiff builds won't run on most distributions due to symbol mismatches (and vice-versa).

Regards,
Roger

+<h2>Building on all systems with CMake</h2> CMake may be used to +generate build files for most common build systems and IDEs, and +supports all UNIX-like systems as well as Windows. See +the <a href="http://www.cmake.org/">CMake website</a> for further +details. To build the software on you need to first run +<tt>cmake</tt> to configure the build and generate the system-specific +build files. This reads the top-level <tt>CMakeLists.txt</tt> file, +which probes the target system for necessary tools and functions, +checks any options you specified to configure the build, and then +outputs build files configured for your system. If using <tt>Unix +Makefiles</tt>, once configuration is done, you simply +run <tt>make</tt> (or <tt>gmake</tt>) to build the software and +then <tt>make install</tt> to do the installation. �B
