ported from c105b729

EMBED_CUDA and FORCE_EMBED_OPENCV flags added to cmake macro add_android_project;
INSTALL_CUDA_LIBRARIES option added to OpenCV.mk
opencv_dynamicuda library installation with enabled OPENCV_INSTALL_MODULES flag fixed;
CUDA initialization apportunity added to OpenCVLoader.initDebug();
Tutorial-4-CUDA sample reimplemented with static OpenCV and CUDA initialization.

Linker dependencies to all OpenCV modules are invalid.
We should not include other bindings in this list (like "opencv_python").

This will allow to disable modules between cmake runs

Allow to build samples via OpenCV binaries from distribution package
(find_package with OpenCV_DIR).

* There's no OPENCV_BINARY_DIR variable;
* No need to append CMakeFiles/CMakeTmp, as CMake does it for you;
* Output variables are unused;
* Wrong usage of CMAKE_FLAGS;
* Small quoting and style issues.

We don't really need it, it makes the code longer, and it can lead to
inconsistent paths when OpenCV is itself inside a symlink.
