error: unknown type name

[freespirit83xyz]

Hello,
I'm new in embedded development and I have an issue.
I have a Raspberry Pi Pico and Pimoroni Display. I need to configure an USB Host for communication with an external device.
I'm developing with VS Code.
Looking at Tinyusb examples, I'm trying to redo "cdc_msc_hid" but some constants, structs are not found by compiler.
On main.cpp board and usb are initialized but on file hid_app.c there are some errors:

• HID_KEYCODE_TO_ASCII
• tuh_hid_report_info_t
• hid_keyboard_report_t
• hid_mouse_report_t

and others are not found.

Here my CMakeLists.txt file

cmake_minimum_required(VERSION 3.12)

Thanks in advance for your help
