Hi Brad, Thanks for the answer.
Yes, I am going to write my own macro which, I hope, will do the job for the most cases. My use case is to generate the LLVM bitcode artefacts *.bc from existing CMake target instead of a binary that it would produce by default. Cloning existing target and then patching its settings will help me to maintain both original and patched versions of a library targets. I think this feature might be very useful for all R&D projects that do all sorts of analysis or transformations based on LLVM IR: instead of a normal process of compilation of everything then linking, such project just consumes a collection of *.bc files and then does some useful work with it. It is definitely the attempt to use CMake slightly beyond its normal use case. For full background please see my other related question: https://cmake.org/pipermail/cmake-developers/2017-January/029788.html Thanks, Stan On Wed, Mar 22, 2017 at 1:06 PM, Brad King <brad.k...@kitware.com> wrote: > On 03/22/2017 03:30 AM, Stanislav Pankevich wrote: > > I have a target `MyTarget`.
