`cmake-rn` fails if projects emit more than one dynamic library

[kraenhansen]

I made the assumption earlier that cmake projects wouldn't emit more than a single dynamic library:

react-native-node-api/packages/cmake-rn/src/platforms/android.ts

Line 146 in a7cc35a

assert.equal(result.length, 1, "Expected exactly one library file");

This won't be the case if we want to run the Node.js tests where the gyp-to-cmake will produce CMakeLists.txt files declaring multiple output files with different names:

cmake_minimum_required(VERSION 3.15)
project(tests-node-api-test_buffer)

add_library(test_buffer SHARED test_buffer.c ${CMAKE_JS_SRC})
set_target_properties(test_buffer PROPERTIES PREFIX "" SUFFIX ".node")
target_include_directories(test_buffer PRIVATE  ${CMAKE_JS_INC})
target_link_libraries(test_buffer PRIVATE ${CMAKE_JS_LIB})
target_compile_features(test_buffer PRIVATE cxx_std_17)
target_compile_definitions(test_buffer PRIVATE NAPI_VERSION=10)

add_library(test_finalizer SHARED test_finalizer.c ${CMAKE_JS_SRC})
set_target_properties(test_finalizer PROPERTIES PREFIX "" SUFFIX ".node")
target_include_directories(test_finalizer PRIVATE  ${CMAKE_JS_INC})
target_link_libraries(test_finalizer PRIVATE ${CMAKE_JS_LIB})
target_compile_features(test_finalizer PRIVATE cxx_std_17)

if(MSVC AND CMAKE_JS_NODELIB_DEF AND CMAKE_JS_NODELIB_TARGET)
  # Generate node.lib
  execute_process(COMMAND ${CMAKE_AR} /def:${CMAKE_JS_NODELIB_DEF} /out:${CMAKE_JS_NODELIB_TARGET} ${CMAKE_STATIC_LINKER_FLAGS})
endif()
