[CMake] find_package and install

[Craig Scott]

Have a look for install_qt4_executable. We've been using that instead of having to explicitly install the Qt libraries ourselves. Much easier to maintain and it seems to deal well with all the platform differences.

PS: I'm going from memory so I might have the name of that function slightly wrong.

In this example that means if cmake_build_type is equal "release" then the optimized library is used. If cmake_build_type is equal "debug" then the debug library is used. This is a simple description of what happens.
