build(cmake): add compiler and generator validation for C++20 modules#281
Merged
Conversation
Add pre-configuration checks for C++20 module build support: - Detect AppleClang which lacks module dependency scanning - Verify Ninja or Visual Studio generator is used - Provide clear warning messages when modules are disabled This enables graceful fallback to header-only build on unsupported configurations instead of cryptic CMake errors. Closes #277
