Setting up HDRI in ImageMagick

[Gary Roach <gary719_list1@verizon.net>]

Hi all,

Does anyone have experience with setting up High Dynamic Range Imaging 
with ImageMagick. The instructions say to run ./configure --enable-hdri 
at the command line. On Debian Stretch with KDE desktop and bash konsole 
this returns command not found. This is the only procedure that I have 
been able to find.

Any help will be sincerely appreciated.

Gary R.
