This command specifies compiler choices to make use of when compiling a given goal. These choices are added to the compile line after choices added by `CMAKE_CXX_FLAGS` or `CMAKE_C_FLAGS` variable or the corresponding goal properties. For instance, `target_compile_options(my_target PRIVATE /WX)` would add the `/WX` flag, enabling warnings as errors, particularly for the compilation of `my_target`. Choices will be specified as `PRIVATE`, `PUBLIC`, or `INTERFACE` to regulate how they propagate to dependent targets.
Specifying compiler flags on a per-target foundation presents vital benefits over globally modifying flags. This granular management permits builders to fine-tune compilation settings for particular person elements, guaranteeing optimum code technology and conduct with out unintended negative effects on different elements of the venture. This observe turns into significantly essential in giant tasks with various codebases and dependencies. Traditionally, managing compiler flags was usually finished globally, resulting in potential conflicts and difficult-to-maintain construct configurations. The introduction of per-target management marked a major enchancment in CMake’s capability to deal with advanced venture constructions and promote extra strong builds.
