As you can see there's no 'd' appended to the executable. Also LOCATION returns the wrong target name.
Steps To Reproduce
Additional InformationThe issue also affects the Visual Studio generator:

test_dll: E:/cmake-test/$(OutDir)/test_dll.dll
test_dll: E:/cmake-test/DEBUG/test_dlld.dll
--------------------------8<------------------

You can't add a proper post_build target with the output of LOCATION... :(

There is a documentation bug. The CMAKE_DEBUG_POSTFIX variable only affects library targets. Furthermore, the LOCATION property cannot be made to work with per-configuration executable names for various reasons (compatibility, VS IDE support, etc.).

In CMake 2.6 and above you don't need the LOCATION property. You can just name the target in the command. Furthermore, the DEBUG_OUTPUT_NAME property can change the name of an executable.

  add_executable(foo foo.c)
  set_property(TARGET foo PROPERTY DEBUG_OUTPUT_NAME foo_d)
  add_custom_command(TARGET foo POST_BUILD COMMAND foo)

Okay, there is one more detail. The CMAKE_DEBUG_POSTFIX variable is just used to *initialize* the target property DEBUG_POSTFIX when a (non-executable) target is created. Setting the property directly does work on any target:

  set_property(TARGET foo PROPERTY DEBUG_POSTFIX _d)

I'll update the documentation of the variable.
