[CMake] cpack hello world, empty packages - novice warning

[Mark Lohry]

1) where is the best place for documentation for cmake/cpack? Is there any
free equivalent to the autotools book? the sporatic examples coupled with
sparse documentation hasn't made the transition as simple as expected :)

2) sorry for the novice nature of this question, but I'm just not seeing
what I'm missing when trying to build a package with cmake/cpack. After
running "cmake .", and "cpack" or "make package", I end up with empty
packages. The tar.gz and tar.Z archives are empty. I was expecting the same
behavior as "make dist" with autotools. Any help with this embarassingly
simple question would be appreciated.



CMakeLists.txt:
cmake_minimum_required( VERSION 2.6 )
project( hello )
set( hello_SRCS hello.cpp )
add_executable( hello ${hello_SRCS} )
include( CPack )
