generateCMakeContent function

String generateCMakeContent(String pluginName, List<String> moduleLibs, String nitroNativePath, { List<({bool isAndroidCpp, bool isNativeCpp, String lib, String module})>? moduleInfos, String? linkChecksum, })

Generates the full content of a fresh src/CMakeLists.txt.

pluginName is the main plugin library name. moduleLibs are additional module library names. nitroNativePath is kept for API compatibility; the generated file uses the local src/native copy populated by nitrogen link. moduleInfos drives per-module C++ decisions.

Implementation
