fatal error: esp_random.h: No such file or directory .

[caseyryan]

I've installed ESP 1.0.6 and there is indeed no library that includes this file. I even tried to install ESP-IDF to the system but to no avail. I also tried to add the path to a directory containing that header file to c_cpp_properties.json -> includePath. It didn't work as well (the intellisense saw that but it still didn't compile and threw the same error).
Any ideas ho to fix this?

p.s. I'm working in vscode
