Linking error: libzlib

hi!

I try to cross-compile OpenCV for arm as described in the tutorial and have the following problem: I get following error after starting make:

When I start cmake I get the following warning: cmake -DCMAKE_TOOLCHAIN_FILE=../armgnueabi.toolchain.cmake../../.. -- Detected version of GNU GCC: 49 (409) -- Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR) -- Could NOT find PythonLibs (missing: PYTHON_INCLUDE_DIRS) (Required is at least versio ...
