Remove FindSQLiteCpp.cmake

It's not needed since the automatically generated file
SQLiteCppConfig.cmake already exists.

Added a small section to the README to explain how it can be used when
this library is installed to the system.

Fixes #283

+#### Using SQLiteCpp on a system-wide installation
+
+If you installed this package to your system, a `SQLiteCppConfig.cmake` file will be generated & installed to your system.  
+This file lets you link against the SQLiteCpp library for use in your Cmake project.
+
+Here's an example of using this in your CMakeLists.txt
+```cmake
+# You can optionally define a minimum version in this call
+find_package(SQLiteCpp REQUIRED)
+# For this example, lets say you created an target with add_executable (or add_library) called "my_target"
+# You can optionally declare PUBLIC or PRIVATE linkage here, depending on your needs.
+target_link_libraries(my_target PRIVATE SQLiteCpp)
+```
+
 #### CMake and tests
 A CMake configuration file is also provided for multi-platform support and testing.
