Linking error after upgraded from pio espressif 2.1.0 to 3.0.0

Had a project that compiled fine with PIO and platform=espressif32 version 2.1.0. Upgraded to espressif32 version 3.0.0. Now I am getting a linking error. It appears to be due to my OTA ca_cert file (located in server_certs/ca_cert.pem)

Any help would be appreciated.

That line target_add_binary_data(${COMPONENT_TARGET} "server_certs/ca_cert.pem" TEXT) should be added to src/CMakeLists.txt
