./configure--prefix Effect
If you do not specify prefix, the executable file is placed by default in/usr/local/bin, and the library file is placed by default in/usr/local/lib, and the configuration file is placed by default in/usr/local/etc. Other resource files are placed in the/usr/local/share. You want to uninstall this program, either in the original make directory with the made uninstall (if the make file specified uninstall), or go to the above directory to delete the relevant files by hand.
Specify prefix, delete a folder directly is enough.
