Install custom QEMU version

[iParcelBox]

The version of QEMU installed by IDF Tools in ESO-IDF 5.4.1 seems to be tagged to 9.0.0. However, this does not include support for esp32s3.

I understand that I need to install the latest fork from https://github.com/espressif/qemu, which I've done and complied all OK.

However, in VSCode when I try and run any of the QEMU commands (or even just `qemu-system-xtensa -version`) it always still points to 9.0.0.

Please could somebody help me by pointing out what I need to do to make VSCode Espressif Extension use the correct version of QEMU?
