After the above change, one of our applications that uses libjpeg-turbo fails to build. It fails with: | CMake Error at .../recipe-sysroot/usr/lib/cmake/libjpeg-turbo/libjpeg-turboTargets.cmake:77 (set_target_properties): | The link interface of target "libjpeg-turbo::turbojpeg" contains: | | ZLIB::ZLIB | | but the target was not found. Possible reasons include: | | * There is a typo in the target name. | * A find_package call is missing for an IMPORTED target. | * An ALIAS target is missing. | | Call Stack (most recent call first): | .../recipe-sysroot/usr/lib/cmake/libjpeg-turbo/libjpeg-turboConfig.cmake:37 (include) | code/CMakeLists.txt:20 (find_package) I can solve it by adding find_package(ZLIB REQUIRED) to the code/CMakeLists.txt file, but is that really expected? I would have assumed that whatever CMake files libjpeg-turbo installs should take care of that automatically. //Peter
