targetlinklibrariestarget

targetlinklibrariestarget refers to the process of linking a target to one or more libraries in build systems such as CMake, where the relevant command is target_link_libraries. In this context, a target represents an executable or library that is defined by add_executable or add_library in a CMakeLists.txt file. The target_link_libraries command associates the specified target with library dependencies that must be linked during the build. It accepts a variety of arguments, including system libraries, other project targets, and interface libraries, allowing fine‑grained control over link order, visibility, and interface propagation. The syntax typically follows: target_link_libraries(<target> [PRIVATE|PUBLIC|INTERFACE] <items>...), where PRIVATE libraries are used only for the target’s own build, PUBLIC libraries are transitive to consumers of the target, and INTERFACE libraries are only used by consumers. This mechanism is essential for ensuring correct linkage, avoiding duplicate symbols, and enabling modular build configurations. Effective use of target_link_libraries promotes cleaner project structure, reduces link-time errors, and supports encapsulation of implementation details.
