title: Compile issues with curlpp: undefined reference to symbol 'curl_easy_setopt@@CURL_OPENSSL_3'
body: <h1>Brief account of the issue:</h1>
  
  <p>After installing curlpp, I attempted to compile c++ code which uses the curlpp library and got the following error:</p>
  
  <pre><code>g++ testCurl.cpp -lcurlpp
  /usr/bin/ld: /tmp/ccx5aH5P.o: undefined reference to symbol 'curl_easy_setopt@@CURL_OPENSSL_3'
  //usr/lib/x86_64-linux-gnu/libcurl.so.4: error adding symbols: DSO missing from command line
  collect2: error: ld returned 1 exit status
  </code></pre>
  
  <p>Any ideas how to fix this?</p>
  
  <h1>More detail:</h1>
  
  <p>I first attempted to install curlpp from source, but after running ./config, I was informed that I need boost (it's a new computer so I did not already have it installed). I installed boost. Then I was informed I needed "a working version of curl" or something like that. After a quick internet search, I found that I needed to install some version of libcurl-dev. In particular I installed the package: libcurl4-openssl-dev 7.35.0-1ubuntu2.2  After this, curlpp compiled and installed without issue.</p>
  
  <p>Finally, I took some generic test code and attempted a compile using the command g++ test.cpp -lcurlpp. This led to the above error. I tried uninstalling curl and everything related and re-installing it. I also tried installing some of the alternate libcurl-dev implementations. Same error.</p>
  
  <p>I have poked around the net for solutions and tried several other things. Nothing has worked so far.</p>
  
  <p>Thanks in advance for any help!!</p>
