cmakeModuleTarget function

String cmakeModuleTarget(String lib, { bool isCpp = false, bool isAndroidCpp = false, })

Returns the CMake target block for a secondary module library.

lib is the snake_case library name. isCpp true when android/linux uses direct C++ for this module. isAndroidCpp true only when android uses C++ directly — when false and isCpp is true, HybridXxx.cpp is wrapped in if(NOT ANDROID) so Android Kotlin builds skip the C++ impl stub.

Implementation

String cmakeModuleTarget(String lib, {bool isCpp = false, bool isAndroidCpp = false}) {
  final className = _toPascalCase(lib);
  // Impl file is always added via a separate target_sources call below (not
  // inlined into add_library's file list) so it can be overridden per-caller
  // via NITRO_IMPL_SRC — see _implSourcesBlock. Android C++: unguarded
  // (compiled on every platform this target builds for). Linux-only C++:
  // guarded with if(NOT ANDROID) so Android Kotlin builds skip it.
  final implSources = isCpp ? _implSourcesBlock(lib, className, unguarded: isAndroidCpp) : '';
