Subject: DevIL plugin: use IL_ CMake variables
X-Git-Tag: 7.0.0~17^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b5f4448a3f3a70e14ba7d6990b81506cbda82180;p=graphviz

DevIL plugin: use IL_ CMake variables

https://cmake.org/cmake/help/latest/module/FindDevIL.html#result-variables
mentions that FindDevIL CMake module sets the following, frustratingly
inconsistent variables:

- IL_LIBRARIES
- IL_INCLUDE_DIR
- DevIL_FOUND

Note I can't actually test this on my local machine, so I'll be relying
on CI.

Fixes #2289
