Summary0014668: Modules/Platform/Darwin.cmake failure with cross toolchain file
DescriptionUsing a toolchain file to test a linux-to-darwin cross-compile, I get
the following:

CMake Error at /usr/share/cmake/Modules/Platform/Darwin.cmake:344 (list):
  list sub-command REMOVE_DUPLICATES requires list to be present.
Call Stack (most recent call first):
  /usr/share/cmake/Modules/CMakeSystemSpecificInformation.cmake:36 (include)
Steps To Reproducecmake -DCMAKE_TOOLCHAIN_FILE=/path/to/Toolchain-OSX-ppc.cmake

FWIW, the toolchain file looks like this:

SET(CMAKE_SYSTEM_NAME Darwin)

SET(CMAKE_C_COMPILER /opt/cross_osx-ppc/bin/powerpc-apple-darwin9-gcc)
SET(CMAKE_CXX_COMPILER /opt/cross_osx-ppc/bin/powerpc-apple-darwin9-g++)

# where is the target environment
SET(CMAKE_FIND_ROOT_PATH /opt/cross_osx-ppc)

# adjust the default behaviour of the FIND_XXX() commands:
# search headers and libraries in the target environment, search
# programs in the host environment
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
Additional InformationLIST(REMOVE_DUPLICATES ...) seems sensitive to unset (non-existent)
variables, so applying the following patch makes it work for me:
