CMake has a GLOB function that allows you to get a list of all files
matching a certain expression. However, it's use is generally
discourages, because it doesn't play well with caching.

Example:
- Your CMakeLists.txt installs all text files with "*.txt"
- You run cmake. It expands the pattern to a list of files and stores
these in the cache. Everything works great.
- You add a new .txt file, but don't update CMakeLists.txt because the
existing pattern should handle it.
- You rerun cmake, but because the CMakeLists.txt hasn't changed,
CMake just uses the existing CMakeCache.txt.
- You build and install, but your new file doesn't get installed,
because CMake doesn't know it's there.

So if you use GLOB you had better get use to doing "cb; rm
CMakeCache.txt; cs". For example libkdegames/carddecks/decks uses
globs, which makes adding new card backs a bit of a hassle.
