Description

Having issues building a host test for a component that uses the component manager to manage a dependency, that then also needs to mock said dependency for the host test.

-- building ESP EVENT MOCKS
-- building FREERTOS MOCKS (only task, event-groups and queue)
-- building esp-idf-cxx MOCKS (I2C only)
CMake Error at /home/vbox/esp/esp-idf/tools/cmake/component.cmake:249 (message):

Expected behaviour

Able to mock a component that is managed by idf_component.yml

@ljden, thank you for reporting the issue.

The mocking support and component manager were developed independently, and we will investigate the issue to find a solution.
