How to change package destination folder in CPack?

问题:

I have a multiple module CMake project with a root CMakeLists.txt with multipe add_subdirectory macros.

As far as I understand the default for CPack/CMake is to create package in project root folder, where root CMakeLists.txt resides. I would like to create a separate install module, with its own folder and create packages there? How to do this?

回答1:

Take a look at the CPACK_TOPLEVEL_TAG and the CPACK_PACKAGE_FILE_NAME variables in the documentation.

回答2:

To get the created packages in the "packages" subdirectory of your build directory, use:

SET(CPACK_OUTPUT_FILE_PREFIX packages)
