target definitions do not trickle down to LLVM IR executable and library definitions #7

e.g., adding a preprocessor definitions with target_compile_definitions holds for the bitcode target but not for the exec and lib target provided by LLVM IR utils.

This mainly concerns the linking phase.

However, all the relevant variables (e.g. CMAKE_SHARED_LINKER_FLAGS) work during the linking phase.

Any separately set target properties (e.g. LINK_DEPENDS) should also be set for the relevant bitcode targets. This is duplication of work, but it can be avoid with a trivial user-defined macro.

The rationale behind this is that the bitcode targets might require different stuff during linking and leaving this as is provides for such needed flexibility.
