I'm trying to install Slash on a Linux Mint system.

$ ./configure --with-lib-dir=/usr/lib/i386-linux-gnu/

Could not find libcurl (used -lcurl)
Please make sure it is available before building Slash

The directory /usr/lib/i386-linux-gnu/ contains:

libcurl-gnutls.so.3
libcurl-gnutls.so.4
libcurl-gnutls.so.4.2.0
libcurl-nss.so.3
libcurl-nss.so.4
libcurl-nss.so.4.2.0
libcurl.so.3
libcurl.so.4
libcurl.so.4.2.0

I assume I'm doing something wrong. How can I get ./configure to detect libcurl?

Try configuring with --verbose.

If you can't get curl working, configure with --no-ext=curl

It looks like your system is missing curl/curl.h
