Fixed CMakeLists.txt to be consistent with module.mk
Converted PX4_TICKS_PER_SEC to define for QURT to get around relocation error
Added stubs for QURT so building a full executable can be tested. This will
enable CI testing without the full Hexagon SDK.

evert parent dir need to know about all build targets.
This approach goes back to the previous way of centralizing the build
dirs in a single file.
