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 manage how they propagate to dependent targets.
Specifying compiler flags on a per-target foundation provides important benefits over globally modifying flags. This granular management permits builders to fine-tune compilation settings for particular person parts, making certain optimum code era and habits with out unintended unwanted effects on different elements of the mission. This follow turns into significantly essential in massive initiatives with numerous codebases and dependencies. Traditionally, managing compiler flags was typically accomplished 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 advanced mission buildings and promote extra strong builds.
