Dear All,
In my code I'm trying to do something slightly tricky. I include packages that
provide imported libraries (amongst other things). Then, because of how my
project is structured, I don't make use of the imported libraries directly, but
first make "copies" of them, and then make use of these copies in my build.
(The reason is that I allow the project to override libraries that are
available from the base packages as well. In which case components using this
overridden library need to use this instance instead of the imported one. But
if no such override is in place, I need to give the library a name that the
components in the project expect to find it with.)
If there would be a way in CMake to "clone" an imported library with a new
name, that would be perfect for my use case. Since as far as I know there's no
such thing, I use code like:
...
add_library( ${libName} SHARED IMPORTED GLOBAL )
# Check which builds it is available for:
get_property( _builds TARGET ${prefix}_${libName}
PROPERTY IMPORTED_CONFIGURATIONS )
set_property( TARGET ${libName} PROPERTY
IMPORTED_CONFIGURATIONS ${_builds} )
...
Now, I recently started producing MODULE and INTERFACE libraries as well. So
the first line in this code is no longer correct for all the imported
libraries. Plus, for INTERFACE libraries the get_property call on
IMPORTED_CONFIGURATIONS just fails with an error message.
So now I wonder: Is there a target property on INTERFACE libraries that I could
use to identify them? Like how there is the target property IMPORTED on the
imported libraries.
Cheers,
Attila
