CPack seems to generate the debian package in a temporary directory then copy it to the destination folder. Is there a way for CPack to delete the temporary debian package? For large packages, it takes up twice the disk space. Also from CI, I can't use a generic wildcard match to pickup all .deb files without picking up the temporary ones.

cmake_minimum_required(VERSION 3.1)

project(foo NONE)

install(
    FILES
        foo.txt
    DESTINATION
        /usr/share/doc/foo
)

set(CPACK_GENERATOR "DEB")
set(CPACK_PACKAGE_NAME ${CMAKE_PROJECT_NAME})
set(CPACK_DEBIAN_PACKAGE_DEBUG "ON")
set(CPACK_DEBIAN_PACKAGE_MAINTAINER "FooBar Inc.")
set(CPACK_DEBIAN_PACKAGE_ARCHITECTURE "any")
include(CPack)

  • What is "generic wildcard match"? Do you mean `globstar` and `**/*.deb` pattern? Why not use just `${topbuilddir}/*.deb` then? – zaufi Jun 22 '22 at 22:30
  • About copy files, as I see in sources CPack always produces files in the _temporary_ location and then **copy** 'em to the `${topbuilddir}`. However, on the systems (and filesystems) supporting _copy-on-write_ it'll use it! Meaning, that it won't take much time and space.... – zaufi Jun 22 '22 at 22:32
