#
# This is a CMake makefile.  CMake is a tool that helps you build C++ programs.
# You can download CMake from http://www.cmake.org.  This CMakeLists.txt file
# you are reading builds dlib's example programs. 
#
# To compile this program all you need to do is ask cmake.  You would type
# these commands from within the directory containing this CMakeLists.txt
# file:
#   mkdir build
#   cd build
#   cmake ..
#   cmake --build . --config Release
#
# The cmake .. command looks in the parent folder for a file named
# CMakeLists.txt, reads it, and sets up everything needed to build program.
# Also, note that CMake can generate Visual Studio or XCode project files.  So
# if instead you had written:
#   cd build
#   cmake .. -G Xcode
#
# You would be able to open the resulting Xcode project and compile and edit
# the example programs within the Xcode IDE.  CMake can generate a lot of
# different types of IDE projects.  Run the cmake -h command to see a list of
# arguments to -G to see what kinds of projects cmake can generate for you.  It
# probably includes your favorite IDE in the list.
