CPack multiple packages with own dependencies

I have a problem creating two debian packages with CPack and CMake. I've done the example from here and I did manage to create two different debian packages, but I want each of them have their own dependencies. The resultant CMakeLists.txt is the following:

cmake_minimum_required(VERSION 2.8.0)
project(MyLib)

add_library(mylib mylib.cpp)

add_executable(mylibapp mylibapp.cpp)
target_link_libraries(mylibapp mylib)

install(TARGETS mylib 
  ARCHIVE
  DESTINATION ~/Downloads/ComponentExampleStart/lib
  COMPONENT libraries)

install(TARGETS mylibapp
  RUNTIME
  DESTINATION ~/Downloads/ComponentExampleStart/bin
  COMPONENT applications)

install(FILES mylib.h
  DESTINATION ~/Downloads/ComponentExampleStart/include
  COMPONENT headers)

file(WRITE dummy_main1.c "int main(int argc, char** argv){return 0;}")
add_executable(dummy_main1 dummy_main1.c)
INSTALL (FILES ${CMAKE_CURRENT_SOURCE_DIR}/dummy_main1 DESTINATION /tmp COMPONENT headers OPTIONAL PERMISSIONS OWNER_EXECUTE GROUP_EXECUTE WORLD_EXECUTE)

file(WRITE dummy_main2.c "int main(int argc, char** argv){return 0;}")
add_executable(dummy_main2 dummy_main2.c)
INSTALL (FILES ${CMAKE_CURRENT_SOURCE_DIR}/dummy_main2 DESTINATION /tmp COMPONENT mylibapp OPTIONAL PERMISSIONS OWNER_EXECUTE GROUP_EXECUTE WORLD_EXECUTE )

SET (CPACK_GENERATOR "DEB")
SET (CPACK_SOURCE_GENERATOR TGZ)
SET (CPACK_DEBIAN_PACKAGE_SHLIBDEPS ON)
SET (CPACK_SET_DESTDIR "on")
set(CPACK_DEB_COMPONENT_INSTALL ON)
set(CPACK_PACKAGE_NAME "MyLib")
set(CPACK_PACKAGE_VENDOR "CMake.org")
set(CPACK_PACKAGE_DESCRIPTION_SUMMARY "MyLib - CPack Component Installation Example")
set(CPACK_PACKAGE_VERSION "1.0.0")
set(CPACK_PACKAGE_VERSION_MAJOR "1")
set(CPACK_PACKAGE_VERSION_MINOR "0")
set(CPACK_PACKAGE_VERSION_PATCH "0")
set(CPACK_PACKAGE_INSTALL_DIRECTORY "CPack Component Example")
set(CPACK_COMPONENTS_ALL applications libraries headers)
set(CPACK_COMPONENT_APPLICATIONS_GROUP "Runtime")
set(CPACK_COMPONENT_LIBRARIES_GROUP "Development")
set(CPACK_COMPONENT_HEADERS_GROUP "Development")
set(CPACK_COMPONENT_LIBRARIES_DEPENDS "libxml2")
set(CPACK_COMPONENT_HEADERS_DEPENDS "libxml2")

set(CPACK_DEBIAN_PACKAGE_DEPENDS "libusb-1.0-0")
SET (CPACK_PACKAGE_CONTACT "Example ")
SET (CPACK_PACKAGE_FILE_NAME "${CMAKE_PROJECT_NAME}_${VERSION}_${CPACK_DEBIAN_PACKAGE_ARCHITECTURE}")

include(CPack)

(NOTE dummy_main1 and dummy_main2 make shlibdeps work, because it needs at least one executable for each package).

My objective is to create 2 different debian packages with different dependencies, say for example:

MyLib_1.0.0_amd64-Developers.deb --- depends on ---> libxml2
MyLib_1.0.0_amd64-Runtime.deb --- depends on ---> lubusb-1.0-0

but I don't find the CPACK macro to do that. I've read a lot of forums and documentation but none of that I've tested work for me. The CPACK_DEBIAN_PACKAGE_DEPENDS macro works fine, but it set the same dependencies for both packages. Is there any way to archieve my goal? I'm using CMake 2.8 to do this.

Thanks!

Solution

  • Well I've finally managed to isolate the dependencies. The problem was the version of CMake I was using (2.8). This can be done in lastest releases (currently using 3.3) with the CPack macro: CPACK_DEBIAN__PACKAGE_DEPENDS
