Hello CMake-developers!
In one of the LLVM sub-projects we have a problem where we need to
install object files, which doesn't seem like a particularly easy
task. I'm curious if anyone has any advice on how to approach this
problem.
The patch is currently being reviewed here:
https://reviews.llvm.org/D28791
Since the object files have fairly simple compile commands our current
approach is to compile the files in custom commands, then use
install(FILES...). This is workable, but I'm wondering if there is a
better way. They do need to be object files, static archives would not
work because these specially named files are handled by linkers and
other tools that we don't control.
Also more of a workaround but perhaps you could create static libraries
but extract them with e.g. CMAKE_AR (toolchain specific) during either
installation e.g. install(CODE|SCRIPT) or as a POST_BUILD custom command.
An OBJECT library might be better suited in theory but I don't think it
currently allows installation and the location of the object files is
generator specific (and afair not always known to cmake).
By doing a manual extraction of the archive you'd be in control over
where the objects go.
