[CMake] The output of cpack is an empty file

[pellegrini]

Hello everybody,

I would like to use cpack in order to gather a set of executables (built 
statically) into a single archive that could be extracted everywhere the 
user wants.

My project architecture is the following:

collections\
    CMakeLists.txt
    prog1\
       CMakeLists.txt + source files
    prog2\
       CMakeLists.txt + source files
    prog3\
       CMakeLists.txt + source files

where each CMakeLists.txt files are stand-alone CMake projects 
(historically each program still has to be "buildable" alone) that 
produces prog1, prog2, prog3 executables.

My main CMakeLists.txt looks like:

##########################################
project(collections)

add_subdirectory(prog1)
add_subdirectory(prog2)
add_subdirectory(prog3)

set(CPACK_GENERATOR "ZIP")
set(CPACK_PACKAGE_DESCRIPTION_FILE "${CMAKE_CURRENT_SOURCE_DIR}/README")
set(CPACK_PACKAGE_NAME "collection of progs)
set(CPACK_PACKAGE_FILE_NAME "collections")
set(CPACK_PACKAGE_VERSION_MAJOR "1")
set(CPACK_PACKAGE_VERSION_MINOR "0")
set(CPACK_PACKAGE_EXECUTABLES "collections")
include(CPack)
##########################################

when running cmake and then nmake package, the built is done, cpack is 
launched but the resulting archive is empty. No README inside and more 
disturbing no
prog1, prog2, prog3 executables. I may have miss something when reading 
the examples but I still have not found what. Would you have any idea ?

thanks a lot

Eric
