[ndnSIM] How to use a non-standard ndnSIM install paths

[Yoshimichi Nakatsuka]

Hi Chris and Philipp,

I'm also using ndnSIM from a non-standard location and I've went through 
a lot of trouble when doing so.
Here are some steps you could follow:

1. After you "exported" your custom paths, you should run "ldconfig". 
This command tells the machine to configure its run time libraries.
2. Don't forget to configure, build, and install your ndnSIM files 
*with* the "--prefix" flag.
     For example, the command will be like:
cd <ns-3-folder>
    ./waf configure --boost-includes=[boost-path]/include 
--boost-libs=[boost-path]/lib --enable-examples --prefix=[custom-path]
    ./waf --prefix=[custom-path]
    ./waf install -prefix=[custom-path]
3. You should then check whether you can run some sample simulations 
with your ndnSIM.
      e.g.) ./waf --run=ndn-simple

Running a simulation using the Scenario Template Structure is a little 
bit different from when you are running a simulation directly from the 
ns-3-folder.

4. The Scenario Template has its own waf that needs configuration.
     e.g.)
cd <scenario-template-folder>
./waf configure --prefix=[custom-path]
5. Then check whether you can run your simulation file from your 
Scenario Template folder.
     e.g.) ./waf --run=your-custom-simulation

When you get an error when configuring ndnSIM (i.e., running ./waf 
configure) and you are sure that you have installed all the 
dependencies, your LD_LIBRARY_PATH or your PKG_CONFIG_PATH (or both) 
could be wrong.
When you get an error when building ndnSIM (i.e., running ./waf), most 
of the time your simulation file has something wrong.

Hope that this helps!

Best,
Yoshimichi
