ESP-IDF BLE GATT client demo not building, build.ninja not found

[usmanmehmood55]

Hi.

I just recently installed the ESP-IDF and used the VS-Code extension with it.
I built some simple C programs, and the blinky program. All those worked perfectly.
But when I built a new project with BLE GATT client as a template, it just doesn't build. I have made no changes to it whatsoever, just the exact demo Espressif gave.
It gives the following error

Code: Select all

ninja: error: loading 'build.ninja': The system cannot find the file specified.

Am I missing something here? Or doing something wrong?
Any help would be greatly appreciated.
