- Remove the CMake < 3.9 hack for setting the GENERATOR_IS_MULTI_CONFIG variable, since we no longer support CMake < 3.15. - Link with the proper C run-time library when building a Debug configuration using the Ninja Multi-Config generator on Windows. - Use the $<CONFIG> generator expression instead of the deprecated CMAKE_CFG_INTDIR variable. $<CONFIG> has existed since CMake 3.0. CMAKE_CFG_INTDIR has been deprecated since 3.21 and is poorly supported with the Ninja Multi-Config generator. - Extend support for the Ninja Multi-Config generator to the Un*x packaging system. Fixes #926
libjpeg-turbo is a JPEG image codec that uses SIMD instructions to accelerate baseline and progressive JPEG compression and decompression on systems with common CPU architectures. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.) libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated derivative of libjpeg v6b developed by Miyasaka Masaru. The TigerVNC and VirtualGL projects made numerous enhancements to the codec in 2009, and in early 2010, libjpeg-turbo spun off into an independent project, with the goal of making high-speed JPEG compression/decompression technology available to a broader range of users and developers. libjpeg-turbo is an ISO/IEC and ITU-T reference implementation of the JPEG standard.
