purge remove flashrom on raspberry pi 0

On the raspberry pi 0 I installed the packages. Then I ran sudo make, I think. 
Which resulted in an error. I then installed libusb-1.0.0-dev. Ran sudo make. This time no error messages. I then ran sudo make install. First messages appeared to be correct.  Then a lot of text, which looked not correct, displayed on the screen.
I pressed esc several times. Ran sudo make install several times. 
Then the make install ran without the strange looking messages.
Maybe flashrom is now correctly installed. I do not know how to verify.
How do I purge remove flashrom, such that I can redo a sudo make? Thank you.
