fix: Remove CMakeLists from packaged examples

[rhinoella]

Remove unecessary CMake files from Dissolve example data.

Unfortunately it's not that simple! The examples get registered as tests, hence the CMakeLists.txt. What you'll have to do instead is modify the examples/package-examples bash script to exclude the CMakeLists.txt from the generated zip...

I'd suggest that neater way would be to modify the find command:

FILES=( $(find ./ -mindepth 2 -type f -not -regex '.*/_.*' -not -name CMakeLists.txt) )
