I want to control multiple FPGAs. For instance, I want to set a "start" bit to 1'b1 for all designs in multiple FPGAs.
What is a good way to achieve this instead of pressing push buttons for multiple FPGAs at the same time.
Thanks in advance.

The questions is a bit too open ended to really answer.
But lets start with the obvious basic solution - route one push-button to multiple FPGAs. Does this meet your requirements? If not, why?

That's actually fine. Is there any clever way to hook one FPGA's push button to another FPGA's push button?
How can I establish the connection between two FPGAs? I can't use FMC cable because I will use all the FMC slots for both FPGAs.

I suggest to just route the single push button to multiple FPGAs on the PCB.
However, your reply implies you're using some sort of already designed board (or multiple boards?) that perhaps have some (how many?) FMC connectors. And maybe a push button or two connected to (one of the) FPGAs.
Again, you've given us little to work with. Yes for some sort of communication between FPGAs you need some sort of actual connection between the FPGAs. Tell us more about your hardware setup.
