Struggeling to create a FindWebP.cmake file

Code
1

I tried to follow this guide but I’m having trouble understanding it. Would I not simply give the path to the library were it is on my system?

I’ve created a file FindWebP.cmake with this content:

FindWebP
--------

WebP_INCLUDE_DIRS=/opt/local/include/
WebP_LIBRARIES=/opt/local/lib/

This doesn’t even produce an error but is completely ignored. Yes, I put the file in the folder that I exported for CMAKE_MODULE_PATH.

Reading the guide above it seems like it’s actually a lot more complicated. What’s the point of calling find_package again in the FindWebP.cmake file?

Here’s an example of about how simple it can get. You can probably skip the version extraction logic.

Note that the content you posted isn’t valid CMake code. You can use the --debug-find flag when configuring to inspect what’s going on when CMake is searching for such things.
