When building PHP from source, third-party Openssl does not pull up, how to fix it?

Question

PHP

Server on Debian GNU/Linux 8.11 (jessie)
The software package is preinstalled by default, namely PHP 7.3 and OpenSSL 1.0.1t

There was a need to install PHP 7.4.11 and OpenSSL 1.1.1h in parallel without affecting the main software package. Compile from sources into separate folders. To do this, I first compiled and installed OpenSSL 1.1.1h, into the /usr/local/ssl/ folder, and then PHP. When configuring and rebuilding PHP, options were specified to use third-party OpenSSL 1.1.1h from the /usr/local/ssl/ folder, but as a result, PHP still uses OpenSSL 1.0.1t that comes with the preinstalled software. How to fix the situation?

When installing PHP from source, the following commands are used (in particular, the --with-openssl=/usr/local/ssl option):

make clean

CONFIGURE_STRING="--prefix=/usr/local/php7.4.11
--enable-fpm
--enable-mysqlnd
--enable-mbstring
--enable-pdo
--enable-phar
--with-openssl=/usr/local/ssl
--with-config-file-path=/usr/local/php7.4.11
--with-config-file-scan-dir=/usr/local/php7.4.11/etc/conf.d
--with-curl
--with-phar
--with-gd
--with-fpm-user=www-data
--with-fpm-group=www-data
--with-mysql-sock=/var/run/mysqld/mysqld.sock
--with-mysqli=mysqlnd
--with-zlib
--without-sqlite3
--without-pdo-sqlite"

./configure $CONFIGURE_STRING && make && make install

Checking the version of OpenSSL used in PHP: Result output:
/usr/local/php7.4.11/bin/php -i | grep -i openssl

What to do, how to fix the situation? Spent a whole day trying to figure it out...
