You can edit the environment variables graphically in Windows (e.g., this, or this).

Add a System variable with name GDAL_DATA and value of the path to the shared GDAL data (a folder with a several files, like coordinate_axis.csv, gcs.csv, pcs.csv, and other files).

To make the environment variable effective, you need to run cmd.exe, or log-out, or other method.

Anaconda / Miniconda users

GDAL library and command-line tools are available via (e.g.) conda install gdal

The GDAL_DATA variable is properly set when the environment is activated. This is done for you if you start an Anaconda Prompt, otherwise you can activate the environment as documented.
