install and use the 'pacman' utility (available from the MSYS2
site), see the instructions below -- it will automatically install
all the dependencies.
Emacs will find these libraries if the directory they are installed
in is on the PATH or in the same directory where you have emacs.exe.

* Installing 64-bit optional libraries from the MSYS2 site
We recommend that you use the 'pacman' utility to download the
libraries you need and all of their dependencies. If you don't have
'pacman' installed, proceed as follows:
. Install the MSYS2 64-bit (x86_64) installer, named
msys2-x86_64-YYYYMMDD.exe (where "YYYYMMDD" is the release date,
like 20160205) from
. Run the installer, select the installation directory, make sure
"Run MSYS2 now" checkbox is checked, and click "Finish". A Bash
window will open.
. Type into the Bash window the following command:
pacman -Sy pacman
When asked whether to proceed with installation, type Y.
To install the optional libraries, start the MSYS2 Bash window and
type the following command:
pacman -S PACKAGES
where PACKAGES is the list of packages you want to install. The
full list is as follows:
mingw-w64-x86_64-xpm-nox mingw-w64-x86_64-libtiff mingw-w64-x86_64-giflib
mingw-w64-x86_64-libpng mingw-w64-x86_64-libjpeg-turbo
mingw-w64-x86_64-librsvg mingw-w64-x86_64-libxml2 mingw-w64-x86_64-gnutls
You can type any subset of this list. Once again, when asked
whether to proceed with installation, answer Y.
Alternatively, you could install the packages manually from this
However, the packages there are not self-contained, so you will need
to download all their dependencies as well.
After the installation, if you will be installing Emacs in a
directory different from where the DLLs were installed, we recommend
to add the directory with DLLs to your PATH, so that Emacs will be
able to find those DLLs.
* Uninstalling Emacs
If you should need to uninstall Emacs, simply delete all the files
