In which context do you run this piece of CMake script?
Is it inside a CMakeLists.txt or is it in a separate script?

Could you try:
execute_process(
    COMMAND ${CMAKE_COMMAND} -E echo "WD  = ${CMAKE_CURRENT_SOURCE_DIR}/
someSubdirectory"
    COMMAND ${CMAKE_COMMAND} -E tar xzf mySDK.tar.gz
    WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/someSubdirectory
    )

and check the value of WD = ...
