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 could be specified as `PRIVATE`, `PUBLIC`, or `INTERFACE` to manage 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 parts, guaranteeing optimum code technology and habits with out unintended unintended effects on different elements of the mission. This follow turns into notably essential in massive initiatives with various codebases and dependencies. Traditionally, managing compiler flags was typically performed globally, resulting in potential conflicts and difficult-to-maintain construct configurations. The introduction of per-target management marked a big enchancment in CMake’s means to deal with complicated mission buildings and promote extra strong builds.
