Need help about apache 2.4.46 configuration on rhel 7.2!!! (HTTPD_ROOT)

Question

The first time I installed Apache 2.4.46 from source downloaded on the Internet , I just run ./configure && make && make install, so the default directories for this are :

ServerRoot = /usr/local/apache2
DocumentRoot = /usr/local/apache2/htdocs

However, my team-lead need to install with ServerRoot=/etc/httpd and

DocumentRoot=/var/www/html

Thus, I remove /usr/local/apace2 folder and reinstall with command ./configure --prefix=/etc/httpd --docdir=/var/www/html and then, make && make install.

The problem is when I start apache, it has an error that:

 httpd: Could not open configuration file /usr/local/apache2/conf/httpd.conf: No such file or directory

I then run /etc/httpd/bin/apachectl -V command and found out that the HTTP_ROOT is still associated with /usr/local/apache.

[root@localhost ~]# /etc/httpd/bin/apachectl -V
    -D HTTPD_ROOT="/usr/local/apache2"
    -D SUEXEC_BIN="/usr/local/apache2/bin/suexec"
    -D DEFAULT_PIDLOG="logs/httpd.pid"
    -D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
    -D DEFAULT_ERRORLOG="logs/error_log"
    -D AP_TYPES_CONFIG_FILE="conf/mime.types"
    -D SERVER_CONFIG_FILE="conf/httpd.conf"

Hence, my question is, how can I change this PATH for HTTPD_ROOT like this

HTTPD_ROOT=/etc/httpd

Thanks a lot for all your support, guys and I'll appreciate it!
