[CMake] Getting empty package with CPack

[Tim Gallagher]

Nils,

Thanks! That definitely got my files into the package, I would have never figured that one out!

I have another, related question though. Maybe what I'm doing cannot be done, but I would like to have a different file layout when building a package than when using make install. I thought if I did:

set(CPACK_INSTALL_CMAKE_PROJECTS "${PROJECT_BINARY_DIR};LESLIE;ALL;/bin")

then all of my targets would go in <package name>/bin even though when I run `make install` all of my targets just go to $CMAKE_INSTALL_PREFIX. The way users who only have access to our binaries would use our code is very different from the way people who have access to our source tree would use the code and I need to figure out a way to package it that way.

Is it at all possible to have an install tree be unique when using CPack vs using the installation in CMake? Is that something that if I want to do, I'd have to use CPack outside of our CMake system? 

Thanks,

Tim

When I run 'make package', it generates my .sh file. But then when I run the extractor, it just creates an empty folder. I would have expected it to create `<package name>/bin/leslie.x`, `<package name>/bin/run_leslie.py` and `<package name>/bin/run_leslie.sh`.

Try with relative install destinations e.g. "DESTINATION ." instead of 
"DESTINATION ${CMAKE_INSTALL_PREFIX}".
Relative paths are already relative to CMAKE_INSTALL_PREFIX by default 
where appropriate and many CPack generators can not handle absolute paths.
