Cmake started reporting incorrect version for zlib. dev-util/cmake-3.26.5-r2 sys-libs/zlib-1.3-r1 CMakeLists.txt (3 lines): cmake_minimum_required(VERSION 3.13) FIND_PACKAGE(ZLIB REQUIRED) message(STATUS "ZLIB VERSION: ${ZLIB_VERSION}") When running "cmake ." I get following line: ZLIB VERSION: 1.3.#define ZLIB_VERSION "1.3" Expected output: ZLIB VERSION: 1.3 or at least: ZLIB VERSION: 1.3.0 It looks like cmake expects 3 digits in component but gets only 2. Due to that media-libs/opencolorio, versions 2.2.1 and 2.3.0 at least, generate invalid cmake file "/usr/lib64/cmake/OpenColorIO/OpenColorIOConfig.cmake", which contains lines like: if (NOT TARGET ZLIB::ZLIB) # ZLIB_VERSION is available starting CMake 3.26+. # ZLIB_VERSION_STRING is still available for backward compatibility. # See https://cmake.org/cmake/help/git-stage/module/FindZLIB.html if (1.3.#define ZLIB_VERSION "1.3") # 1.3.#define ZLIB_VERSION "1.3" find_dependency(ZLIB 1.3.#define ZLIB_VERSION "1.3") else() find_dependency(ZLIB 1.3.#define ZLIB_VERSION "1.3") endif() endif() Due to that malformed file, media-libs/openimageio fails to merge. Reproducible: Always Steps to Reproduce: 1. Run cmake with CMakeLists.txt from above. Incorrect version string is reported. OR: 1. emerge -1 =dev-util/cmake-3.26.5-r2 =sys-libs/zlib-1.3-r1 =media-libs/opencolorio-2.3.0 2. emerge -1 =media-libs/openimageio-2.5.4.0 Actual Results: openimageio fails to emerge: CMake Error at /usr/lib64/cmake/OpenColorIO/OpenColorIOConfig.cmake:63: Parse error. Function missing ending ")". End of file reached. Call Stack (most recent call first): src/cmake/modules/FindOpenColorIO.cmake:35 (find_package) src/cmake/checked_find_package.cmake:127 (find_package) src/cmake/externalpackages.cmake:177 (checked_find_package) CMakeLists.txt:166 (include) Expected Results: openimageio successfully emerges
This should be fixed in cmake 3.27.4: https://gitlab.kitware.com/cmake/cmake/-/commit/903439495033da40f798db9ec064d9b16ea672fc
3.27.x is stable now on amd64.
