Well not quite.
I tried that, but my current definition is rather
Target_link_libraries(B interface B_imported)
I don't remember for which reason I had to do it in 2 stages like that (the
A/A_imported and B/B_imported versions)
If I add A in the list to read :
Target_link_libraries(B interface B_imported A)
Then linking against B does add B_imported and A, but it does not keep the link
order and might put B_imported before A on the command line.
I'll try with property INTERFACE_LINK_LIBRARIES instead, and will also try to
remove those 2 stages...
With regards
David
