I can confirm that replacing the text libtbb.so file containing the 
INPUT instruction with a link to the library with the SONAME is 
sufficient to solve the problem, at least as a short term workaround. 
There is no importing of targets: this library is found with 
find_library as part of a config.cmake file invoked as part of 
find_package(). I don't know whether CMake is using readelf, objdump or 
readlink, but it appears that something of that nature is being tried (a 
quick search with ack revealed cmELF.{h,cxx}). If interpreting the INPUT 
directive were to be added to that procedure, I think we would be very 
happy. Should I put an entry in Mantis?

Thanks,
Chris.
