Error using AzureIotHubClientV2 library

I have created a simple project where I am using AzureIotHubClientV2 library.

It gives me following error when “COMPILING APPLICATION FOR DEBUG”.

cannot open source file “<mbedtls_config.h>” (dependency of “AzureIotHubClientV2.h”)

If I “COMPILING APPLICATION & DEVICE OS” it is working.

Any idears?
