===========================================
Example project using Bob's C++ interface
===========================================
This example project shows a way to incorporate Bob's C++ libraries into a C++ project.
For this, is uses the CMake_ interface, and a home-developed ``FindBob.cmake`` file.
It relies on the python interface to download and install Bob_.
More information about the Bob installation can be found on its `webpage <http://www.idiap.ch/software/bob>`_.

Building this example
---------------------
As the example requires some Bob_ packages to be installed, we first run one of the ways to install Bob_, i.e., using `buildout <https://github.com/idiap/bob/wiki/Installation#using-zcbuildout-for-production>`_.
For that, simply go to the main directory of this package and call::
$ python bootstrap-buildout.py
$ ./bin/buildout
This will checkout some of the packages to the ``src`` directory, and download some into the ``eggs`` directory.
If you have Bob installed globally, it will use the globally installed packages instead of downloading new eggs.
If you have Bob installed in a non-default directory, for example in an `virtual environment <https://github.com/idiap/bob/wiki/Installation#using-pip-for-experts>`_, you can use that python version to bootstrap.
Inside of this package I have prepared a small CMake_ project that includes some of the Bob_ packages.
It uses the ``FindBob.cmake`` to locate Bob's include directories and libraries.
To enable that, you can use the ``find_package(Bob COMPONENTS <package(s)> REQUIRED)`` command to find the list of bob ``package(s)``.
Later, you can use three CMake_ variables ``Bob_INCLUDE_DIRS``, ``Bob_LIBRARY_DIRS``, ``Bob_LIBRARIES`` and ``Bob_DEFINITIONS`` and add it to your project::
cmake_minimum_required(VERSION 2.8)
project(test)
# Set the module path so that "FindBob.cmake" is found
set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR})
# Find all Bob packages recursively
find_package(Bob COMPONENTS bob.io.image REQUIRED)
# Add Bob's include directories
include_directories(${Bob_INCLUDE_DIRS})
# Add Bob's library directories
link_directories(${Bob_LIBRARY_DIRS})
# Add Bob's libraries
link_libraries(${Bob_LIBRARIES} boost_system)
# Add Bob's definitions
add_definitions(${Bob_DEFINITIONS})
# create an "my_test" executable from file "test.cpp"
add_executable(my_test test.cpp)
For some reason (that I do not understand) we also need to add the ``boost_system`` library, although it should theoretically be linked to the Bob_ libraries already.
So, now we can go ahead and compile our package using CMake_::
$ mkdir build
$ cd build
$ cmake ..
$ make
and we should get an executable ``my_test`` inside the build directory.
Note that you can pass a variable to CMake to use a custom Bob_ installation::
$ cmake .. -DBOB_PREFIX_PATH=/path/to/your/bob/installation
or set the ``BOB_PREFIX_PATH`` environment variable accordingly.
If you have a local directory containing (some of) the Bob packages inside ``src`` or ``eggs`` sub-directories, you can set the ``BOB_SOURCE_DIR`` variable, which defaults to the directory where the ``CMakeLists.txt`` is located::
$ cmake .. -DBOB_SOURCE_DIR=/path/to/your/local/bob/packages
The evaluation order of the directories is:
1. ``${BOB_SOURCE_DIR}/src``
2. ``${BOB_SOURCE_DIR}/eggs``
3. ``${BOB_PREFIX_PATH}/lib/*/site-packages`` (where * typically is your python version)
4. the system path
To run the example, go back to the package base directory (otherwise it will not find the example image) and call::
$ ./build/my_test
This should create an HDF5 file called ``test.hdf5`` inside the current directory.
