Summary0012265: ${CMAKE_CURRENT_LIST_DIR} called from a macro or function does not refer to the current directory
DescriptionThis might be fully intentional, but I noticed that inside and macro or function the ${CMAKE_CURRENT_LIST_DIR} refers to the caller.

I found a workaround by setting a variable in the top level. Is this a bug or is there another variable I should use?

It behaves the same way as ${CMAKE_CURRENT_LIST_FILE}, so this behaviour is intentional.
I can remember there were discussion(s) about this on the cmake or cmake-developers mailing list, and this was the outcome. Can't remember the details though.

The behavior is as intended.

The workaround you propose is already in common usage. Typically if I'm writing a module "MyModule.cmake" then I will put code at the top like

  get_filename_component(_MyModule_LIST_DIR ${CMAKE_CURRENT_LIST_FILE} PATH)

which is the pre-2.8.3 equivalent to

  set(_MyModule_LIST_DIR ${CMAKE_CURRENT_LIST_DIR})

so I can refer to the module location inside functions or macros later.
