How can i supply a clock (16 Mhz for example) to an external device which has a clock_in pin using STM32Cubemx ?

Depends. Simple would be to use MCO output which is a specific pin alternate which output one of several internal clock source with power of 2 programmable prescaling. Otherwise, simply use a timer pwm generator channel output where frequency and duty cycle is more flexible.
