title: Install R cairo package after installing cairo via conda
body: <p>I'm trying to install the Cairo package for R. I don't have admin rights for the server so I installed Cairo via the conda package manager <code>conda install -c https://conda.anaconda.org/anaconda cairo</code>. I have compiled R from source in my home directory. 
  I have tried to add the following to my bashrc:</p>
  
  <pre><code>export CAIRO_LIBS=-L${HOME}/miniconda/pkgs/cairo-1.12.18-6/lib/cairo/
  export CAIRO_CFLAGS=-I${HOME}/miniconda/pkgs/cairo-1.12.18-6/include/cairo/
  </code></pre>
  
  <p>When I try <code>install.packages('Cairo')</code>, I get the following error:</p>
  
  <pre><code>configure: CAIRO_CFLAGS=-I/N/u/jfreimer/Mason/miniconda/pkgs/cairo-1.12.18-6/include/cairo/

  </code></pre>
  
  <p>Anaconda has an R package of cairo (<a href="https://anaconda.org/r/r-cairo" rel="nofollow">https://anaconda.org/r/r-cairo</a>) so all of the dependencies that I need should be installable via conda. However, I am trying to use the standalone R that I installed and not conda R as I have had trouble with other packages in conda R. I was wondering if anyone has any suggestions </p>
