Unable to Install dm-sqlite-adapter Gem on Windows PC - ruby-on-rails

Question

I am new to Ruby/Sinatra and I am trying to install the DataMapper SQLite Adapter. When I run gem install dm-sqlite-adapter I get the message below. I did previously install sqlite3 using the command gem install sqlite3. However, if I try to call gem install sqlite3 --platform=ruby, I get errors.
c:\Ruby_Dev_Kit>gem install dm-sqlite-adapter
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing dm-sqlite-adapter:

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include

Gem files will remain installed in C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/do_sq
lite3-0.10.13 for inspection.

I have tried multiple different approaches to get around this issue. I was able to install the Ruby Development Kit as I was able to install the JSON gem. Similarly I downloaded the SQLite source code from SQLite.org but I was not able to figure out how to properly configure all aspects of the amalgamation to be found by the tool. Below is the mkmf.log's value:

I tried many different things to get it working, and I realize this may be a stupid question. However, at this point, I am out of ideas. Any assistance would be really appreciated.

I eventually was able to work around this issue. For those who run into this on the future, Bosko Ivanisevic wrote a great guide how to work around this.
See here: http://rubyonwindowsguides.github.io/book/ch02-05.html
Many details in there to be careful about so be sure to read through it step by step and follow everything exactly. Great explanation.
