notes on porting NICE to WIN using CMAKE:
-------

1. Never use GLOB_RECURSE. It's evil. E.g. if you add or remove source files, CMake has no way of knowing that it should be re-run. Just list all the files in your CMakeLists.txt (or, if you think the list is excessively long, create a file called e.g. files.cmake, put the list in there and INCLUDE it in the CMakeLists.txt file.
2. Never do in-source builds. CMake creates many, many files, and you don't want to delete them all individually for a clean build. And there's no way to implement a safe "make clean" (e.g. your build system might be running a custom utility which generates files CMake knows nothing about).



fixing all these includes of template definitons:
//#ifdef __GNUC__
#include "core/vector/RowMatrixT.tcc"
//#endif
tcc are not cpps, they need to be included into the header file otherwise template usage will result in linking errors

------------------------------------------
porting core/basics/timer.h/cpp
highly unix dependend
better use 3rd party time functionality for now()
better use
boost::timer ??

---------------------------
stringtools highly os dependented
->recursive dir scan with "ls -r" syntax!!
use 3rd party lib like boost oder qt
use boost regex for regex syntax in stringtools::regex bla

#### geile funktionen der OpenCV:
---aus OpenCVUtils.cmake:
macro(ocv_convert_to_full_paths VAR) # convert list of paths to full paths
macro(ocv_get_real_path VAR PATHSTR) # get absolute path with symlinks resolved
macro(ocv_list_add_suffix LST SUFFIX) # add suffix to each item in the list
macro(ocv_list_add_prefix LST PREFIX) # add prefix to each item in the list
macro(ocv_list_unique __lst)# stable & safe duplicates removal macro



OpenCVModule.cmake
ocv_glob_modules(pathcurrdir) -->in modules
  in jedem untermodel, eg core
  ocv_add_module(modname)
    sets variable "the_module" => set(the_module opencv_${name})
    extra abhängikeitens über zweites argument in der funktion, eg. ocv_add_module(core ${ZLIB_Lbla})
  ocv_module_include_directories() ( auch mit zusatzincludes dann übergeben ${ZLib_include_Dir})
  ocv_glob_module_sources() holt cpps und hpp h aus unterordnern -- sources bilden
  ocv_create_module (binary build the module ->add_library,  set_target etc
