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 may be specified as `PRIVATE`, `PUBLIC`, or `INTERFACE` to manage how they propagate to dependent targets.
Specifying compiler flags on a per-target foundation gives important benefits over globally modifying flags. This granular management permits builders to fine-tune compilation settings for particular person elements, making certain optimum code technology and habits with out unintended unwanted effects on different components of the venture. This follow turns into notably essential in massive tasks with numerous codebases and dependencies. Traditionally, managing compiler flags was typically carried out globally, resulting in potential conflicts and difficult-to-maintain construct configurations. The introduction of per-target management marked a major enchancment in CMake’s potential to deal with complicated venture constructions and promote extra sturdy builds.
