In case anyone needs to support both Cocos2d-x v3 and v4, and doesn't want to use the CMakeLists.txt that's in the github repo which copies the spine source into the cocos2d/editor-support/spine folder, then this is a working script:
get_target_property(COCOS2D_X_VERSION cocos2d VERSION)
if (COCOS2D_X_VERSION VERSION_GREATER_EQUAL 4.0)
set(SPINE_COCOS_X_VERSION_DIR "v4")
else()
set(SPINE_COCOS_X_VERSION_DIR "v3")
endif()
set(SPINE_COCOS2DX_HEADER
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/AttachmentVertices.h
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/SkeletonAnimation.h
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/SkeletonBatch.h
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/SkeletonRenderer.h
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/SkeletonTwoColorBatch.h
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/spine-cocos2dx.h
)
set(SPINE_COCOS2DX_SRC
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/AttachmentVertices.cpp
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/SkeletonAnimation.cpp
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/SkeletonBatch.cpp
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/SkeletonRenderer.cpp
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/SkeletonTwoColorBatch.cpp
${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src/spine/spine-cocos2dx.cpp
)
list(APPEND SPINE_COCOS2DX_SRC ${SPINE_COCOS2DX_HEADER})
add_library(spine-cocos2dx-static STATIC ${SPINE_COCOS2DX_SRC})
set_target_properties(spine-cocos2dx-static
PROPERTIES
ARCHIVE_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/lib"
LIBRARY_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/lib"
)
add_dependencies(spine-cocos2dx-static spine-static cocos2d)
target_link_libraries(spine-cocos2dx-static
PUBLIC spine-static
PRIVATE cocos2d
)
target_include_directories(spine-cocos2dx-static PUBLIC ${CMAKE_CURRENT_LIST_DIR}/${SPINE_COCOS_X_VERSION_DIR}/src)
The folder structure is as follows:
gamename/external/spine/CMakeLists.txt (with the above script)
gamename/external/spine/v3/src/spine
gamename/external/spine/v4/src/spine
You may want to add the following to your root game CMakeLists.txt to get rid of the spine folder in the cocos2d/editor-support path (and avoid the header file errors):
execute_process(
COMMAND ${CMAKE_COMMAND} -E remove_directory "${CMAKE_CURRENT_SOURCE_DIR}/cocos2d/cocos/editor-support/spine"
)
Then to use the spine-cocos2dx-static lib, add the following to the gamename/CMakeLists.txt:
add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/external/spine-cocos2dx ${PROJECT_BINARY_DIR}/spine-cocos2dx)
get_target_property(spine_cocos2dx_INCLUDE_DIRS spine-cocos2dx-static INTERFACE_INCLUDE_DIRECTORIES)
target_include_directories(${APP_NAME} PRIVATE spine_cocos2dx_INCLUDE_DIRS)
target_link_libraries(${APP_NAME} spine-cocos2dx-static)
