They have not been fully tested and probably need some more work 20and setup. They might benefit from additional shell or Python scripts. 21 22There are autoconf makefiles (Makefile.in) and Visual C++ project files (.vcproj) 23in the subfolders. They are copied over from the ICU source tree and will not 24work without modifications. However, I started to use CMake (CMakeLists.txt) 25which is much simpler, and if it works well enough then I plan to just 26delete the old makefiles and project files. The CMake files should 27work on Linux and MacOS X. 28I should use more variables to make the CMake files more portable, and should 29use ICU's installed icu-config or Makefile.inc to get the values for these 30variables. 31(If and when ICU itself uses CMake, we should be able to point to its modules.) 32 33Things will improve as I work on Unicode 6... 34 35markus 36
