[CMake] FILE command working

[Michael Wild]

It works for me if I use

file(STRINGS test.txt test_str)
foreach(line IN LISTS test_str)
  message("line = ${line}")
endforeach()

Problem is that empty lines result in empty elements in test_str, which are discarded by the old-style foreach loop over a list.
