Remove deleted files from CMake install routines

[KonradNoTantoo]

On master, cmake install fails because CMake/CMakelists.txt references files that have been removed from github

set(INST_FILES Packages/FindOIS.cmake Packages/FindOGRE.cmake Packages/FindOgreProcedural.cmake Utils/FindPkgMacros.cmake Utils/PreprocessorUtils.cmake Utils/ProceduralConfigTargets.cmake Utils/ProceduralMacros.cmake )

Packages/FindOIS.cmake and Packages/FindOGRE.cmake are the culprits.

can you provide a pull-request?

[KonradNoTantoo]

I'm a bit uneducated regarding github usages. Please excuse me.

I'm supposed to fork to be able to commit and produce a PR, is that it?

[KonradNoTantoo]

Well, seems I managed to do that by myself. I feel like an adult now.

Fork merged, closing issue.
