If you really have done that then any Squid built after will auto-detect 
it there and link to that new OpenSSL version using only the 
"--with-openssl" build option.

If you actually built the newer OpenSSL and placed it somewhere 
non-default then you should build Squid using "--with-openssl=/path" 
where the path is the *base* directory under which you installed 
OpenSSL.

I.e. using --with-openssl=/path literally, autoconf will look for 
/path/include/openssl/*.h and /path/lib/openssl.a and add the -I and -L 
compiler flags automatically for you if all the required pieces are 
actually found there and working. Or will exit with an error stating 
what parts are broken.

The method Yuri pointed out (adding the compiler flags manually) can 
also work, but none of the ./configure testing is done to verify the 
things there are working. So Squid will be built with all OpenSSL bug 
workarounds disabled, and if any were needed or the openssl install is 
broken you will not find out until much later in the build process.


PS. same goes for any software correctly using autoconf --with/--without 
options to link libraries.
