in one of our projects, we use copy_if_different to copy some DLLs
required by the runtime. It's called as post-build action. The problem
is that several targets want to copy the same DLLs, and when using
parallelized builds, the different "cmake -E copy_if_different" can
conflict, leading the whole build to fail.
I see two options to fix this:
1. don't use copy_if_different, but a custom tool that can deal with the
concurrency
2. instead of adding post-build actions to different targets, fill up a
list containing all the files required, and add a single post-build
action to a single target that copies all the required files in one go
What do you think?
Had the same problem and went with #2
Hi Caleb,
could you give some more details how you did this? Filling up the list
is easy, but I am not sure how to define the final action that will copy
all the DLLs, and make sure it happens only once. Did you define a new
custom target for that?
