Hello, I'm new to OpenCV and try to build OpenCV (without any special plugin) with Eclipse on my Laptop with Win7 64bit. For this I followed the "Installtion in Windows"-Tutorial, using TDM-GCC 32bit Compiler and CMake 2.8.12.2 ( Version 3.0.0 gives me an Error with CMP0026). In CMake I choose "EclipseCDT-MinGW Makefile", make my selection, press configure and then generate.
Btw. is it ok, if there are missing paths to modules I do not want to use? E.g. CLAMDBLAS or Java Path)?
After I have opened the generated project with Eclipse(Import exiting code with Makefile) I try to start building, but after a few seconds I get the following Error:
Errors occurred during the build. Errors running builder 'CDT Builder' on project 'OpenCVBuilding'. Internal error building project OpenCVBuilding configuration Default Generated resource conflict: two resources of the same name: /OpenCVBuilding/Default/[Targets]/[lib] zlib/Source Files/zutil.o generated by different tools tool1: GCC C Compiler tool2: GCC C Compiler

So I tried building OpenCV on my Desktop using TDM-GCC 64bit (everything else unchanged) with the same Error. Due to this I choose a MinGWMakefile in CMake and directly use mingw32-make.exe from TDM-GCC(both 32bit and 64bit). I also tried building OpenCV with Code::Blocks but both (Codeblocks and wingw32-make) gave me this Error:

I'm deeply grateful if somebody can help me und tell me what I'm doing wrong. Thank you.
