I ran the following lines
cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D INSTALL_C_EXAMPLES=ON \ -D INSTALL_PYTHON_EXAMPLES=ON \ -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.0.0/modules \ -D BUILD_EXAMPLES=ON and got this error
CMake Error: The source directory /home/pi/opencv-3.0.0/build/BUILD_EXAMPLES=ON does not exist`How could this be solved?

The last argument to the cmake command needs to be a directory containing a CMakeList.txt file.
Usually that's either the current directory . or the parent directory .. in the case of an out-of-source build where you are running the command from a separate build subdirectory:
cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D INSTALL_C_EXAMPLES=ON \ -D INSTALL_PYTHON_EXAMPLES=ON \ -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.0.0/modules \ -D BUILD_EXAMPLES=ON ..[I suspect you are following instructions that used .. and misinterpreted it as standing in for an arbitrary list of -D options rather than an actual directory argument]
