# PATCHED by scripts/patch-bindings.sh -- do not hand-edit; see that script.
#
# The ubrn template resolves 'uniffi-bindgen-react-native/package.json', but
# 0.31.0-3 added an "exports" map that does not expose "./package.json", so
# require.resolve throws ERR_PACKAGE_PATH_NOT_EXPORTED. execute_process leaves
# OUTPUT_VARIABLE empty on failure, the include path silently degrades to
# "/cpp/includes", and the build dies much later with a confusing
# "'UniffiCallInvoker.h' file not found".
#
# Instead resolve the "." export (always present) and walk up to whichever
# directory actually contains cpp/includes. That works whether the package is
# hoisted to the app's root node_modules or nested under this library.
#
# Resolution is anchored to CMAKE_CURRENT_SOURCE_DIR, passed as argv[1]:
# execute_process runs in the *build* directory, which lives under .cxx/ and
# would resolve to the wrong node_modules (or none at all).
