Stop Repeating Include Paths: Encapsulate Usage with CMake Interface Libraries
Declare include paths, compile definitions and transitive links once in a CMake interface library and let linking propagate them. This removes duplication and keeps usage consistent across targets.
cppInterface library CMAKE_CXX_STANDARD propagation to dependent targets in multi-config generators
An interface library declares CMAKE_CXX_STANDARD 17 and exposes compile features through INTERFACE_COMPILE_FEATURES. Dependent executables link against it. The goal is for every consumer to inherit the same C++ standard flag in both Debug and Release configurations when using Visual Studio or Xcode. This assumes CMake 3.8 through 3.28. CMake evaluates CMAKE_
