1. File lists in cmake/Tutorial

CMakeLists.txt

TutorialConfig.h.in

tutorial.cxx

2. File lists in cmake/Tutorial/MathLibs

CMakeLists.txt

MathLibs.h

mysqrt.cxx

3. cmake/Tutorial/CMakeLists.txt

endif (USE_MYMATH)

# add the executable
add_executable (Tutorial.x tutorial.cxx)

5. Configure and Compile

do so  in cmake directory as the followings

cmake -DUSE_MYMATH=on Tutorial

make
