How do I make CMake output into a 'bin' dir?

I'm currently constructing a project with a plugin structure. I'm using CMake to compile the project. The plugins are compiled in separate directories. My problem is that CMake compiles and saves the binaries and plugins, dynamic libraries, in the directory structure of the source. How do I make CMake save the files in something like a ./bin directory?

As to me I am using cmake 3.5, the below(set variable) does not work:

set(
      ARCHIVE_OUTPUT_DIRECTORY "/home/xy/cmake_practice/lib/"
      LIBRARY_OUTPUT_DIRECTORY "/home/xy/cmake_practice/lib/"
      RUNTIME_OUTPUT_DIRECTORY "/home/xy/cmake_practice/bin/"
)

but this works(set set_target_properties):

set_target_properties(demo5
    PROPERTIES
    ARCHIVE_OUTPUT_DIRECTORY "/home/xy/cmake_practice/lib/"
    LIBRARY_OUTPUT_DIRECTORY "/home/xy/cmake_practice/lib/"
    RUNTIME_OUTPUT_DIRECTORY "/home/xy/cmake_practice/bin/"
)

Use this line config:

set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/build/)
place your any CMakeLists.txt project.

This ${PROJECT_SOURCE_DIR} is your current source directory where project place .
and if wander why is ${EXECUTABLE_OUTPUT_PATH} check this file CMakeCache.txt then search the key word output path, all the variables define here, it would give a full explanation of the project all setting.

To add on to this:

If you're using CMAKE to generate a Visual Studio solution, and you want Visual Studio to output compiled files into /bin, Peter's answer needs to be modified a bit:

# set output directories for all builds (Debug, Release, etc.)
foreach( OUTPUTCONFIG ${CMAKE_CONFIGURATION_TYPES} )
    string( TOUPPER ${OUTPUTCONFIG} OUTPUTCONFIG )
    set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/lib )
    set( CMAKE_LIBRARY_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/lib )
    set( CMAKE_RUNTIME_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/bin )
endforeach( OUTPUTCONFIG CMAKE_CONFIGURATION_TYPES )

One more refinement to serg06's answer:

To force the three paths to be used as-is with all generators and for all build configurations, you can add an empty generator expression as in the following:

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "$<0:>${CMAKE_BINARY_DIR}/bin") # .exe and .dll
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY "$<0:>${CMAKE_BINARY_DIR}/lib") # .so and .dylib
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY "$<0:>${CMAKE_BINARY_DIR}/lib") # .lib and .a

That has the side-effect of forcing the Visual Studio generator in particular to use the specified path as-is, instead of appending a configuration-specific subdirectory, with no need for a foreach loop.
