This follows existing patterns (more or less), but
there are certainly opportunities to move more of this
sort of logic into macros defined at the top level.
- added a _stringify function to top CMakeLists
- switched all stringification tasks to use the macro
- all suffixes are now .gen.h instead of .inc (to help cmake track dependencies)
- set OBJECT targets for osd cpu & gpu libs, and use the obj target for
static and dynamic linking
- add a new examples_common_obj OBJECT target
- replace direct source dependencies to obj target in all examples CMakeLists
This change makes it possible to not re-compile the same source files
multiple times when they are used in multiple targets. Thanks to jcowles
for uncovering the CMake functionality.
Note: it seems that multi-process build is working again (gmake -j <x>)
