Building openssl and libcurl for linux from source

I am trying to build openssl and libcurl from source. At first glance this looks like it should be very easy, but I can't get my curl build to recognize my openssl libs.

I have tried the following steps:

pwd
$ /home/sossisos/curlssl/
wget https://www.openssl.org/source/openssl-1.0.2i.tar.gz
tar xzf openssl-1.0.2i.tar.gz
cd openssl-1.0.2i
./config
make
cp libcrypto.a libssl.a ../ssl/lib/
cp -R include/ ../ssl/

cd ..
wget https://curl.haxx.se/download/curl-7.50.3.tar.gz
tar xzf curl-7.50.3.tar.gz
cd curl-7.50.3
./configure --with-ssl="/home/sossisos/curlssl/ssl/"

But the config results for curl says

curl version:     7.50.3
Host setup:       x86_64-pc-linux-gnu
Install prefix:   /usr/local
Compiler:         gcc
SSL support:      no      (--with-{ssl,gnutls,nss,polarssl,mbedtls,cyassl,axtls,winssl,darwinssl} )

Further up it also says

checking whether to enable Windows native SSL/TLS (Windows native builds only)... no
checking whether to enable iOS/Mac OS X native SSL/TLS... no
configure: PKG_CONFIG_LIBDIR will be set to "/home/sossisos/curlssl/ssl/lib/pkgconfig"
checking for HMAC_Update in -lcrypto... no
checking for HMAC_Init_ex in -lcrypto... no
checking for ssl_version in -laxtls... no
configure: WARNING: SSL disabled, you will not be able to use HTTPS, FTPS, NTLM and more.
configure: WARNING: Use --with-ssl, --with-gnutls, --with-polarssl, --with-cyassl, --with-nss, --with-axtls, --with-winssl, or --with-darwinssl to address this.

I also tried the following curl config call

LDFLAGS="-L/home/sossisos/curlssl/ssl/lib/" ./configure --with-ssl="/home/sossisos/curlssl/ssl/"

Am I doing something wrong with my openssl build? Or my curl build? Is it not possible to link openssl statically to curl?

The answer turned out to be really simple. All that was needed was adding the "ldl" lib and "--disable-shared" flag to the curl configure call, as such

LIBS="-ldl" ./configure --with-ssl="/home/sossisos/curlssl/ssl/" --disable-shared

And then

make

That's it!
