Subject: [PATCH] CMake: Rename all object targets to obj_<foo>_(debug|release)

This change is necessary to please the cuda wrapper nvcc that insists on
exporting the target name as preprocessor definition. Unfortunately, a
period "." is an invalid character and we end up with warnings of the
form

  "missing whitespace after the macro name"

Fix this by renaming all object targets to only contain underscores.
