Improves the filter for hidden files in "Eigen" and "Eigen/src". This generic solution prevent cmake from having an error .svn folders when the source folder is under subversion.

STYLE: Convert CMake-language commands to lower case Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case.

STYLE: Remove CMake-language block-end command arguments Ancient versions of CMake required else(), endif(), and similar block termination commands to have arguments matching the command starting the block. This is no longer the preferred style.
