CMake: drop support for cmake < 3.5

2024-01-08T17:13:14Z

Compatibility for cmake version < 3.5 is now deprecated in cmake and specifing version below 3.5 in cmake_minimum_required produces a warning.[1] [1] https://cmake.org/cmake/help/latest/release/3.27.html#deprecated-and-removed-features

Require `stdint.h` & `inttypes.h`

2023-09-24T11:54:28Z

With #1450 which goes with 480cc9d49775d018c19ce0e01f6be27858d63d39 "Remove support for non-C99 compilers (like VS2010) that don't support snprintf()", support for MSVC versions prior to vs2015 is dropped: https://stackoverflow.com/questions/2915672/snprintf-and-visual-studio-2010 This means that all supported MSVC versions do have `stdint.h` & `inttypes.h` now. For non windows platforms, those headers were already mandatory. Make them mandatory for all builds.

CMake: add missing GNUInstallDirs related substitutions (fixes #1424) (#1456)

CMake: switch to GNUInstallDirs (#1424)

2022-08-07T14:42:01Z

* 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.

Added support for high throughput (HTJ2K) decoding.

2021-09-25T10:26:59Z

There are a few limitations: - mixed mode (HT and regular code blocks) is not supported. - ROI in HT blocks is not supported. - Placeholder passes are not supported. - MultiHT sets are not support, only a singleHT set. - there are known issues with some compliance testing files related to the parsing of packet header.

cmake: add install interface include directory

Add multithreaded support in the DWT encoder.

2020-05-20T18:30:21Z

Update the bench_dwt utility to have a -decode/-encode switch Measured performance gains for DWT encoder on a Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz (4 cores, hyper threaded) Encoding time: $ ./bin/bench_dwt -encode -num_threads 1 time for dwt_encode: total = 8.348 s, wallclock = 8.352 s $ ./bin/bench_dwt -encode -num_threads 2 time for dwt_encode: total = 9.776 s, wallclock = 4.904 s $ ./bin/bench_dwt -encode -num_threads 4 time for dwt_encode: total = 13.188 s, wallclock = 3.310 s $ ./bin/bench_dwt -encode -num_threads 8 time for dwt_encode: total = 30.024 s, wallclock = 4.064 s Scaling is probably limited by memory access patterns causing memory access to be the bottleneck. The slightly worse results with threads==8 than with thread==4 is due to hyperthreading being not appropriate here.

Changed cmake version test to allow for cmake 2.8.11.x
