CMake target_link_libraries PRIVATE INTERFACE PUBLIC INTERFACE_INCLUDE_DIRECTORIES exported targets include directories
💡 Result:
In CMake, the keywords PRIVATE, PUBLIC, and INTERFACE define how dependencies and their usage requirements (such as include directories) are propagated to other targets [1][2]. When using target_link_libraries, these keywords control the visibility of the link dependency and the propagation of its usage requirements [1][3]. PRIVATE The dependency is used only by the target itself for its own implementation [2][3]. It is not part of the target's public link interface, so consumers of the target do not need to link against this dependency, nor do they inherit its usage requirements (such as INTERFACE_INCLUDE_DIRECTORIES) [1][2]. INTERFACE The dependency is not linked into the target itself, but it is part of the target's link interface [1][3]. This means consumers of the target will inherit the dependency's usage requirements (including its INTERFACE_INCLUDE_DIRECTORIES) and will link against it, but the target itself does not use it for its own implementation [2][3]. PUBLIC This is a combination of PRIVATE and INTERFACE [2]. The dependency is linked into the target, and it is also part of the target's public link interface [1][3]. Consequently, both the target and any consumers of the target will link against it and inherit its usage requirements [1][2]. INTERFACE_INCLUDE_DIRECTORIES and Exported Targets The INTERFACE_INCLUDE_DIRECTORIES property is key to how CMake handles transitive usage requirements [4][5]. When a target is exported via install(EXPORT) or export, CMake automatically generates IMPORTED targets [5]. These generated targets carry the appropriate usage requirements—such as INTERFACE_INCLUDE_DIRECTORIES—so that when a consumer links to these imported targets using target_link_libraries, CMake automatically provides the correct include paths required to compile against the dependency [4][5]. Best Practices It is highly recommended to always specify one of these keywords when using target_link_libraries, as relying on the legacy keywordless signature (which defaults to PUBLIC) can lead to unintended propagation of dependencies and headers [6][3]. When setting include directories, use target_include_directories with the same scoping keywords (PRIVATE, PUBLIC, INTERFACE) to ensure the target's own headers are properly exposed to its consumers [7][8]. Avoid hard-coding absolute paths to dependencies in your export configurations; instead, rely on the INTERFACE_INCLUDE_DIRECTORIES properties of the imported dependency targets themselves [7][5][8].

Make Pthread::Pthread part of Fcitx5Utils’ public usage requirements.
src/lib/fcitx-utils/CMakeLists.txt:153 links Pthread::Pthread with PRIVATE, so downstream targets that only consume Fcitx5::Utils do not inherit ${PTHREAD_INCLUDE_DIR}. The public headers include <pthread.h> under _WIN32 at src/lib/fcitx-utils/event.h, src/lib/fcitx-utils/event_libuv.h, and src/lib/fcitx-utils/eventloopinterface.h, so use PUBLIC here or link consumers directly.
