Packaging packaging in CPack packaging

Question

How to pack multiple packages with cpack. several packages as follows:

A.tar.gz ---bin/hello ---lib/libhello.a ---B.tar.gz ---bin/demo ---lib/libdemo.a 

B.tar.gz included in A.tar.gz

Answer 1

One solution I can think of is to create a custom target that generates B.tar.gz and then uses the install command to add the generated B.tar.gz Below is an example of the CMakeLists.txt file that I used to create the desired result.

 cmake_minimum_required(VERSION 2.8) project(pack_multiple_example) # Create the custom command to tar up the files # wanted in the B.tar.gz set(B_OUTPUT "B.tar.gz") add_custom_target( ${B_OUTPUT} COMMAND tar -czf ${B_OUTPUT} demo libdemo.a DEPENDS demo demo_exe ) install( FILES "${PROJECT_BINARY_DIR}/${B_OUTPUT}" DESTINATION . ) # Create libhello target set(HELLOLIB_SRCS hellolib.c) add_library(hello ${HELLOLIB_SRCS}) install( TARGETS hello ARCHIVE DESTINATION lib LIBRARY DESTINATION lib COMPONENT hello ) # Create hello binary target set(HELLO_SRCS hello.c) add_executable(hello_exe ${HELLO_SRCS}) # Auto-build the B.tar.gz when hello_exe changes add_dependencies(hello_exe ${B_OUTPUT}) target_link_libraries(hello_exe hello) # Set the output name since we use the 'hello' target name # for the library target. set_target_properties(hello_exe PROPERTIES OUTPUT_NAME hello) install( TARGETS hello_exe RUNTIME DESTINATION bin COMPONENT hello ) # Create libdemo target set(DEMOLIB_SRCS demolib.c) add_library(demo ${DEMOLIB_SRCS}) # The install command below is commented out since the # target output is packaged via the custom target above #install( # TARGETS demo # ARCHIVE DESTINATION lib # LIBRARY DESTINATION lib # COMPONENT demo # ) # Create demo binary target set(DEMO_SRCS demo.c) add_executable(demo_exe ${DEMO_SRCS}) target_link_libraries(demo_exe demo) # Set the output name since we use the 'demo' target name # for the library target. set_target_properties(demo_exe PROPERTIES OUTPUT_NAME demo) # The install command below is commented out since the # target output is packaged via the custom target above #install( # TARGETS demo_exe # RUNTIME DESTINATION bin # COMPONENT demo # ) set(CPACK_GENERATOR "TGZ") include(CPack)
