Créer un paquet debian (.deb) d'un projet utilisant CMake

A la source du projet en question, ouvrez le fichier CMakeLists.txt et ajoutez y à la fin :

SET(MAJOR_VERSION 1)
SET(MINOR_VERSION 0)
SET(PATCH_VERSION 0)

IF(EXISTS "${CMAKE_ROOT}/Modules/CPack.cmake")
INCLUDE(InstallRequiredSystemLibraries)

SET(CPACK_SET_DESTDIR "on")
SET(CPACK_PACKAGING_INSTALL_PREFIX "/tmp")
SET(CPACK_GENERATOR "DEB")

find_program(DPKG_CMD dpkg)
execute_process(COMMAND "${DPKG_CMD}" --print-architecture
 OUTPUT_VARIABLE CPACK_DEBIAN_PACKAGE_ARCHITECTURE
 OUTPUT_STRIP_TRAILING_WHITESPACE
)

SET(CPACK_PACKAGE_DESCRIPTION "short description")
SET(CPACK_PACKAGE_DESCRIPTION_SUMMARY "long description ...")
SET(CPACK_PACKAGE_VENDOR "Vendor")
SET(CPACK_PACKAGE_CONTACT "developer ")
SET(CPACK_PACKAGE_VERSION_MAJOR "${MAJOR_VERSION}")
SET(CPACK_PACKAGE_VERSION_MINOR "${MINOR_VERSION}")
SET(CPACK_PACKAGE_VERSION_PATCH "${PATCH_VERSION}")

SET(CPACK_DEBIAN_PACKAGE_PRIORITY "optional")
SET(CPACK_DEBIAN_PACKAGE_SECTION "net")
SET(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6, libgcc1, libstdc++6, libqt5concurrent5, libqt5designer5, libqt5network5, libqt5xml5, libqt5svg5, libqt5x11extras5, libqt5multimedia5, libqt5multimedia5-plugins, libquazip5-1 | libquazip-qt5-1 | libquazip-qt5, libpython2.7-stdlib, libpythonqt-qt5")
SET(CPACK_DEBIAN_PACKAGE_RECOMMENDS "sni-qt, python-crypto")
SET(CPACK_DEBIAN_PACKAGE_SUGGESTS "")
SET(CPACK_DEBIAN_PACKAGE_BREAKS "")   
SET(CPACK_DEBIAN_PACKAGE_CONFLICTS "")
SET(CPACK_DEBIAN_PACKAGE_MAINTAINER "you <you@domain.tld>")
SET(CPACK_DEBIAN_PACKAGE_HOMEPAGE "http://upstream.tld")

SET(CPACK_PACKAGE_FILE_NAME "${CMAKE_PROJECT_NAME}_${MAJOR_VERSION}.${MINOR_VERSION}.${CPACK_PACKAGE_VERSION_PATCH}_${CPACK_DEBIAN_PACKAGE_ARCHITECTURE}")
SET(CPACK_SOURCE_PACKAGE_FILE_NAME "${CMAKE_PROJECT_NAME}_${MAJOR_VERSION}.${MINOR_VERSION}.${CPACK_PACKAGE_VERSION_PATCH}")

SET(CPACK_COMPONENTS_ALL Libraries ApplicationData)

Vous pouvez éditer les variables :

• MAJOR_VERSION, MINOR_VERSION et PATCH_VERSION afin de générer un fichier contenant les bons numéros de version (projet_MAJOR_VERSION.MINOR_VERSION.PATCH_VERSION.deb
• CPACK_DEBIAN_PACKAGE_DEPENDS afin de matcher les dépendances du projet d'origine. Vous pouvez éventuellement retrouver les dépendances dans un paquet .deb du projet avec dpkg --info
• CPACK_DEBIAN_PACKAGE_SECTION afin de définir la section du paquet.
• CPACK_PACKAGE_DESCRIPTION et CPACK_PACKAGE_DESCRIPTION_SUMMARY
• CPACK_PACKAGE_VENDOR et CPACK_PACKAGE_CONTACT

Les différentes variables existantes : https://cmake.org/cmake/help/latest/module/CPackDeb.html et https://cmake.org/cmake/help/latest/module/CPack.html

Pour construire le paquet :

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
cpack ..

Vous pouvez vérifier les fichiers présents dans l'archive .deb et les informations du paquet :

dpkg -c package.deb
dpkg --info package.deb
