The existing scripts for Debian and NSIS packaging were too complex and
dealt unnecessarily with lower level details that should be already
handled by CMake and CPack.
- Packaging-related scripts have been moved to the new cpack/ directory.
There, CPack variables common to all generators are defined in
cpack/common.cmake, and then generator-specific variables are defined
independently (e.g.: cpack/debian.cmake and cpack/nsis.cmake).
- Packaging is now optionally done at a second stage, by running
`cpack -G <generator>` on the build directory. This removes the
requirement to branch based on the system name, and instead all CPack
variables are assigned unconditionally.
- Since now only one version of the game is packaged, there is no need
to maintain the complex scripts in packaging/ and packaging/windows that
used to deal with all variants (e.g.: "wip-cars-and-tracks",
"hq-cars-and-tracks", etc.).
- The use of CPACK_NSIS_EXTRA_INSTALL_COMMANDS,
CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS and CPACK_NSIS_CREATE_ICONS_EXTRA
should not be required, let alone modifying the HKLM registry manually,
since CPack already provides everything required to set up the
installer, the uninstaller and shortcuts.
- $INSTDIR is not required, since NSIS would already prepend the
target installation directory.
- PROJECT_VERSION_METADATA is not a standard CMake variable.
CMAKE_PROJECT_VERSION_TWEAK is instead meant for this purpose. [1]
- OPTION_PACKAGING and OPTION_ALL_IN_ONE_PACKAGING were removed since
packaging will always be available, yet optional. Packagers must then
run CPack on a second stage, as described above.
- Outdated comments were removed to avoid confusion.
TODO:
- Add shortcut to track editor on NSIS.
- dmg packaging was not revamped because of lacking compatible
hardware, but still it has been moved to cpack/dmg.cmake.
- Windows portable packaging (OPTION_PORTABLE_PACKAGING) has been left
out since it required 7z and relied on several hacks to work.
Furthermore, portable versions of the game were already not released on
the latest release, either. [2]
