Dart-related failures in CMake unit tests

[Hsilgos]

While running Xcode-related unit tests for Xcode I met linking issues in two tests:

19:   Undefined symbols for architecture x86_64:
19: 
19:     "_library_execute_finalizer", referenced from:
19:         _library_unit_test_MainBar_register_finalizer in object.module.only.main_main_ffiglue.o
19:     "_Dart_NewFinalizableHandle_DL", referenced from:
19:         _library_unit_test_MainBar_register_finalizer in object.module.only.main_main_ffiglue.o
19:     "_library_uncache_dart_handle_by_raw_pointer", referenced from:
19:         _library_unit_test_MainBar_finalizer in object.module.only.main_main_ffiglue.o 

Failing tests:

     19 - cmake_test.gluecodium_generate/shared-modules-depend-on-object-libs/CMAKE_CXX_VISIBILITY_PRESET-hidden (Failed)
     39 - cmake_test.gluecodium_generate/two-shared-modules/CMAKE_CXX_VISIBILITY_PRESET-hidden (Failed)

Command to run all Xcode-related CMake unit tests:
GLUECODIUM_VERSION_DEFAULT="10.1.7" GLUECODIUM_BUILD_ENVIRONMENT=ios-x86_64 ./run-cmake-unit-test.cmake

Commands to run only failing tests:

GLUECODIUM_VERSION_DEFAULT="10.1.7"  GLUECODIUM_BUILD_ENVIRONMENT=ios-x86_64 CTEST_FILTER="cmake_test.gluecodium_generate/shared-modules-depend-on-object-libs/CMAKE_CXX_VISIBILITY_PRESET-hidden" ./run-cmake-unit-test.cmake

GLUECODIUM_VERSION_DEFAULT="10.1.7"  GLUECODIUM_BUILD_ENVIRONMENT=ios-x86_64 CTEST_FILTER="cmake_test.gluecodium_generate/two-shared-modules/CMAKE_CXX_VISIBILITY_PRESET-hidden" ./run-cmake-unit-test.cmake

CMake test needs to be updated.

I am closing this ticket. On CI tests passed, because missing symbols were allowed. However, when flags were forced to disallow missing symbols, then they started to fail. Dart DL API symbols were missing.

Fixes have been merged to the mainline:
