IntervalTimer -- "Does not name a Type"

[Bewing]

Teensy 4.0, simple code:

#include <avr/pgmspace.h>
#include <cstddef>

IntervalTimer LightsTimer;
void myTask(void) {
}

...results in...

R:\QTRNM-QFSV\Teensy\Quartetronome\Metronome.cpp:4:1: error: 'IntervalTimer' does not name a type
4 | IntervalTimer LightsTimer;
| ^~~~~~~~~~~~~
exit status 1

Compilation error: exit status 1

Searching this, I encounter the "Lightweight Callbacks" thread. (that's where I got the #include ideas from). Sorry to wake a sleeping giant...

You need

#include <IntervalTimer.h>
