Ruby sqlite3 gem installation issue on Windows 10

Question

I am very new to ruby and rails. I am trying to install to sqlite3 for trying a tutorial and having issues. I am on Windows 10 and using ruby 2.6.1p33 (2019-01-30 revision 66950) [x64-mingw32].

Here is the installation error I am getting while running gem install sqlite3-ruby. I have also tried running gem install sqlite3 --platform=ruby -- --with-sqlite3-include=c:/sqlite3/include --with-sqlite3-lib=c:/sqlite3/lib

C:/Ruby26-x64/bin/ruby.exe -I C:/Ruby26-x64/lib/ruby/2.6.0 -r ./siteconf20190217-3116-1d59gcv.rb extconf.rb
checking for sqlite3.h... yes
checking for pthread_create() in -lpthread... yes
checking for -ldl... no
checking for dlopen()... no

*** extconf.rb failed ***
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=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=C:/Ruby26-x64/bin/$(RUBY_BASE_NAME)
    --with-sqlcipher
    --without-sqlcipher
    --with-sqlite3-config
    --without-sqlite3-config
    --with-pkg-config
    --without-pkg-config
    --with-sqlcipher
    --without-sqlcipher
    --with-sqlite3-dir
    --without-sqlite3-dir
    --with-sqlite3-include
    --without-sqlite3-include=${sqlite3-dir}/include
    --with-sqlite3-lib
    --without-sqlite3-lib=${sqlite3-dir}/lib
    --with-pthreadlib
    --without-pthreadlib
    --with-dllib
    --without-dllib

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  C:/Ruby26-x64/lib/ruby/gems/2.6.0/extensions/x64-mingw32/2.6.0/sqlite3-1.4.0/mkmf.log

extconf failed, exit code 1

I have downloaded sqlite3 from their site and here is the folder structure of C:\sqlite3\

sqldiff.exe
sqlite3.exe
sqlite3_analyzer.exe
include\shell.c
include\sqlite3.c
include\sqlite3.h
include\sqlite3ext.h
lib\sqlite3.def
lib\sqlite3.dll

I have also copied sqldiff.exe, sqlite3.exe and sqlite3_analyzer.exe to C:\Ruby26-x64\bin. In my environment variable, I have added C:\sqlite3\ to PATH and also created a new environment variable sqlite3-dir pointing to C:\sqlite3\

Could someone please provide some help for this installation problem?

adding gem 'sqlite3', git: "https://github.com/larskanis/sqlite3-ruby", branch: "add-gemspec" in the project Gemfile file works. After that run bundle install. Make sure to install git in the machine. This is the github link
