Summary:                    POSITION_INDEPENDENT_CODE does not add -pie
Description: 
I tried to make wodim a position independent executable to comply with distro
policies. I did that by adding this to CMakeLists.txt:
SET_TARGET_PROPERTIES(wodim PROPERTIES POSITION_INDEPENDENT_CODE TRUE)

That however does not set -pie for the linker flags so no actual pie binary is
created. An extra "LINK_FLAGS -pie" is necessary. I guess that's not the
intention of the abstraction.


Steps to Reproduce: 
SET_TARGET_PROPERTIES(wodim PROPERTIES POSITION_INDEPENDENT_CODE TRUE)

should result in

$ readelf -h wodim|grep Type:
  Type:                              DYN (Shared object file)
