942ac87e	2025-06-14 07:45:48	Build: Allow disabling tests/command-line tools This is useful for downstream projects that include libjpeg-turbo via ExternalProject_Add(). Closes #818
51cee036	2025-06-13 14:52:09	Build: Use wrappers rather than CMake object libs Some downstream projects need to adapt the libjpeg-turbo source code to non-CMake build systems, and the use of CMake object libraries made that difficult. Referring to #754, the use of CMake object libraries also caused the libjpeg-turbo libraries to contain duplicate object names, which caused problems with certain development tools. This commit modifies the build system so that it uses wrappers, rather than CMake object libraries, to compile source files for multiple data precisions. For convenience, the wrappers are included in the source tree, but they can be re-generated by building the "wrappers" target. In addition to facilitating downstream integration, using wrappers improves code readability, since multiple data precisions are now handled at the source code level instead of at the build system level. Since this will be pushed to a bug-fix release, the goal was to avoid changing any existing source code. A future major release of libjpeg-turbo may restructure the libjpeg API source code so that only the functions that need to be compiled for multiple data precisions are wrapped. (That is how the TurboJPEG API source code is structured.) Closes #817
2351a2d5	2024-09-16 12:30:27	Build: Support LLVM/Windows Since LLVM/Windows emulates Visual Studio, CMake sets CMAKE_C_SIMULATE_ID="MSVC" but does not set MSVC. Thus, our build system needs to enable most (but not all) of the Visual Studio features when CMAKE_C_SIMLUATE_ID="MSVC". Support for LLVM/Windows is currently undocumented because it isn't a standalone build environment. (It requires the Visual Studio and Windows SDK headers and link libraries.) Closes #786
3290711d	2024-06-22 17:45:31	cjpeg: Only support 8-bit precision w/ GIF input Creating 12-bit-per-sample JPEG images from GIF input images was a useful testing feature when the data precision was a compile-time setting. However, now that the data precision is a runtime setting, it doesn't make sense for cjpeg to allow data precisions other than 8-bit with GIF input images. GIF images are limited to 256 colors from a palette of 8-bit-per-component RGB values, so they cannot take advantage of the additional gamut afforded by higher data precisions.

3f43bb33	2024-05-06 13:03:46	Build: Don't use COMPONENT w/install(INCLUDES ...) (Regression introduced by 24e09baaf024e71841a92d30d0e763242ed959ef) The install() INCLUDES option is not an artifact option. It specifies a list of directories that will be added to the INTERFACE_INCLUDE_DIRECTORIES target property when the target is exported using the install() EXPORT option, which occurs when CMake package config files are generated. Specifying 'COMPONENT include' with the install() INCLUDES option caused the INTERFACE_INCLUDE_DIRECTORIES properties in our CMake package config files to contain '${_IMPORT_PREFIX}/COMPONENT', which caused errors of the form 'Imported target "libjpeg-turbo::XXXX" includes non-existent path' when downstream build systems attempted to include libjpeg-turbo using find_package(). Fixes #759 Closes #760
24e09baa	2024-04-12 11:46:21	Build: Add COMPONENT to all install() commands This makes it possible for downstream packagers and other integrators of libjpeg-turbo to include only specific directories from the libjpeg-turbo installation (or to install specific directories under a different prefix, etc.) The names of the components correspond to the directories into which they will be installed. Refer to libvips/libvips#3931, #265, #338 Closes #756
