Specify CMAKE_RUNTIME_OUTPUT_DIRECTORY from outside of the project

Hardcoding this into the library itself means that outside consumers
cannot choose a different value. This in particular breaks the CMake
template project of ours which also tries to set this value.

As conventional wisdom dictates, its best to not touch CMAKE_ variables
unless necessary. Luckily our use of presents means we can easy move
this into the development preset.
