Please check PATH environment variable for ImageMagick installation path.

*** 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=${opt-dir}/include
        --without-opt-include
        --with-opt-lib=${opt-dir}/lib
        --without-opt-lib
        --with-make-prog

        --srcdir=.
        --curdir
        --ruby=C:/Ruby33-x64/bin/$(RUBY_BASE_NAME)

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

ImageMagick-7.1.1-29-Q16-HDRI-x64-dll

The ImageMagick installer has Install development headers and libraries for C and C++ option. When turn on the option, it install libraries into C:\Program Files\ImageMagick-7.1.1-Q16-HDRI\lib.

PS C:\Program Files\ImageMagick-7.1.1-Q16-HDRI\lib> dir

    ディレクトリ: C:\Program Files\ImageMagick-7.1.1-Q16-HDRI\lib

ImageMagick-7.1.1-30-Q16-HDRI-x64-dll

The option changed to Install development headers for C and C++.

[Watson1978]

@dlemstra The latest ImageMagick installer does not install CORE_RL_MagickCore_.lib. Therefore it causes RMagick installation failure.

What would be the best way to deal with this? Or would ImageMagick be able to handle this?

Reported the issue to ImageMagick

Downloading and installing the installer from https://github.com/rmagick/ImageMagick-binaries, it would be a temporary workaround
