If libHelloStelModule.a is a CMake target, you don't need to specify its full path, you can use the target name for most purposes. If that isn't enough, put ${CMAKE_CFG_INTDIR} in the right place. This will resolve to Debug, Release etc. at build time. However, it can be tricky to use this variable correctly, because at CMake time it only expands to $(Configuration) (with the Xcode generator) or . (with the Makefile generator). So you must make sure that Xcode sees the $(Configuration) on the command line in order to get substituted correctly.
