Im not that familiar with Ubuntu. This could be because of the (lazy) Makefile that just compiles including /usr/include/httpd/ and /usr/include/apr-1/ for the header files.
Check where id the file httpd.h and point the directory accordingly. If no httpd.h file is found you might need to install the httpd devel packages (or apache devel, not sure).

@IvnSoft folder "/usr/include/httpd/" doesn't exists on Ubuntu. (We have more servers, and all of them are Ubuntu and this folder doesn't exists) - in Ubuntu it's apache2, not httpd.

So, module "mod_vhost_limit" is not usable for Ubuntu?

In Debian/Ubuntu, the files are placed in /usr/include/apache2 instead of /usr/include/httpd. Running these commands to compile on Debian/Ubuntu:

sudo apt install apache2-dev
ln -s /usr/include/apache2 /usr/include/httpd
ln -s /usr/include/apr-1.0 /usr/include/apr-1

[jmcclelland]

Then install with:

cp mod_vhost_limit.so /usr/lib/apache2/modules/
 echo "LoadModule vhost_limit_module /usr/lib/apache2/modules/mod_vhost_limit.so" > /etc/apache2/mods-available/vhost_limit.load
a2enmod vhost_limit
systemctl reload apache2
