Yes, if I understand your question.  When cpack is used in-conjunction
with cmake, cpack will follow the installation rules specified in your
CMakeLists.txt files.  So cmake will only install the files listed in
the conditionally built ${libzmq_sources} variable if we issue a cmake
INSTALL command with that variable.

If you look at the ZMQ_ADD_LIBRARY macro I created in
cmake/zmq_macros.cmake you will see how the INSTALL command can be
used in cmake.  OR, you can just do 'cmake --help-command INSTALL' for
more details.   CPack will use the install commands to build the
package.  Right now I have only put install commands in for the
zmq_server binary and libzmq.so files.

**NOTE** the library versioning doesn't work quite right at the moment
because you removed the temporary ZMQ_VERSION and ZMQ_VERSION_MAJOR
variables I had created for this.

You can use cpack simply by issuing an include(CPack) at the top of
trunk/CMakeLists.txt file and then issue a 'make package' to generate
the package.  By default I believe it will create a .sh install file.

I typically don't use cpack, but I frequently use the cmake generated
install target.

If you run cmake like this,

cmake -D"CMAKE_INSTALL_PREFIX=$HOME/zmq" /path/to/trunk

make install

will build everything and install it to $HOME/zmq (just like autotools
--prefix=)

Hope that helps,
George.
