Actually, is not 100% your fault ;-)
You need the pre-built binaries besides the source code:
Then you can grab either source or the amalgamation version, we only
care about sqlite3.h which is inside.

need to create the linking library that will be used by gcc to link
against sqlite3 dll.
So, until they provide a ready to use sqlite3 package:
1) create a sqlite3 folder
2) unzip sqlitedll-3_6_0.zip into sqlite3/lib folder
3) unzil from the sources the sqlite3.h file and put into sqlite3/include folder
3) you will need to call dlltool to create the .a library to be able
to compile with gcc:
D:\src\sqlite3\lib>c:\Ruby18\devkit\mingw\bin\dlltool.exe --dllname sqlite3.dll
--def sqlite3.def --output-lib sqlite3.a
4) Now you can supply the --with-sqlite3-dir to gem install:
gem install sqlite3-ruby -- --with-sqlite3-dir=d:/src/sqlite3
Building native extensions. This could take a while...

Maybe we should point this in the Wiki? :-D
Human beings, who are almost unique in having the ability to learn from
the experience of others, are also remarkable for their apparent
disinclination to do so.
