I run the compilation in AWS-linux 2023 as in the readme:

$ ./build.sh
$ ./configure
$ make
$ sudo make install

Now it seems to complete but after restarting the standard Nginx package, with "modsecurity on" added to config, I get:

nginx: [emerg] unknown directive "modsecurity" in (config file)

Is there a step missing to recompile all of Nginx or, enable the module I compiled?
