cmake: Cleanup CMakeLists.txt for all components

- Add missing CMakeLists.txt
- Use POCO_ macros to improve code structure in XCode/VisualStudio
- Better ODBC detection
- Remove unnecessary commented out code

The CMake documentation recommends explicitly listing source files, but because CMake is not the primary build system GLOB patterns are used for the moment.
