Always use full paths in custom commands (and use find_program)

find_program(SLICE2CPP_EXECUTABLE slice2cpp PATHS /opt/Ice-3.3/bin)

set(out_dir "${CMAKE_CURRENT_BINARY_DIR}/.."
set(out_file "${out_dir}/TianShanIce.cpp") add_custom_command(OUTPUT
"${out_file}"
  COMMAND "${SLICE2CPP_EXECUTABLE}"
    -I /opt/Ice-3.3/slice/
    -I "${out_dir}"
    --output-dir "${out_dir}"
    "${CMAKE_CURRENT_SOURCE_DIR}/../TianShanIce.ICE"
  )
add_library(TianShanIce SHARED "${out_file}")

Hope this helps

Michael
