I've added PRIV_REQUIRES mbedtls lwip esp-tls tcp_transport spiffs, should I be adding esp_http_client to here as well?

Hi all, I am creating a custom component with references to esp-idf headers such as this: #include "esp_http_client.h" But I continue to get the following error when I compile: fatal error: esp_http_client.h: No such file or directory Any tips/pointers would be greatly appreciated. Thanks, Ambrose
