vc90 is for MSVC 2008. You should try to match with the version of your compiler
Looking at the information at http://gisinternals.com/stable.php, I'm not sure there is
a version for VS2017 since it uses the old ECW 3.3
(http://gisinternals.com/packageinfo.php?file=release-1911-gdal-2-3-mapserver-7-2.zip)
but the VS2015 package uses SDK 5.3:
http://gisinternals.com/packageinfo.php?file=release-1900-gdal-2-3-mapserver-7-2.zip

In that later case, if you look at the build log of VS2015
http://build2.gisinternals.com/sdk/build-output/vc14-20180809-9-42-22-78-vc14-stable-2.3-7-2.txt
accessible from http://gisinternals.com/status.php,
you could likely try linking against the $(ECWDIR)\lib\vc140\win32\NCSEcw.lib

Or just use the ready-made packages at
http://gisinternals.com/stable.php
