CMake常见示例

# 1. 定义原型动态库（前置条件）
add_library(opgraph_math SHARED
)
# 2. 生成ES API包（库+wheel包）
add_es_library_and_whl(
    ES_LINKABLE_AND_ALL_TARGET es_math
    OPP_PROTO_TARGET  opgraph_math
    OUTPUT_PATH       ${CMAKE_BINARY_DIR}/output
)

# 3. 在应用中使用
add_executable(my_app main.cpp)
target_link_libraries(my_app PRIVATE es_math)

如果工程中还有在编译阶段就需要ES头文件的OBJECT/STATIC中间目标，可额外添加add_dependencies(<中间目标> build_es_math)（build_es_*** 名称会随包名变化），以确保在编译该目标前已完成代码生成。最终的可执行或共享库只需target_link_libraries(... es_math) 即可自动触发相关依赖，示例如下：

add_library(my_obj OBJECT foo.cc bar.cc)
# 保证编译对象前先生成es_math头文件（推荐显式添加）
add_dependencies(my_obj build_es_math)
# 传递头文件搜索路径的作用
target_link_libraries(my_obj PRIVATE es_math)

add_executable(my_app $<TARGET_OBJECTS:my_obj>)
target_link_libraries(my_app PRIVATE
        es_math
)

# 只生成 C/C++ 库（跳过Python wheel包）
add_es_library(
    ES_LINKABLE_AND_ALL_TARGET es_math
    OPP_PROTO_TARGET  opgraph_math
    OUTPUT_PATH       ${CMAKE_BINARY_DIR}/output
)

# 生成math TARGET
# 生成产物不会包含es_Add_c.h; es_Add.h, es_Add.cpp, es_Add.py
add_es_library(
    ES_LINKABLE_AND_ALL_TARGET es_math
    OPP_PROTO_TARGET  opgraph_math
    OUTPUT_PATH       ${CMAKE_BINARY_DIR}/output
    EXCLUDE_OPS       Add
)

# 生成math TARGET
add_es_library_and_whl(
    ES_LINKABLE_AND_ALL_TARGET es_math
    OPP_PROTO_TARGET  opgraph_math
    OUTPUT_PATH       ${CMAKE_BINARY_DIR}/output
)

# 生成nn TARGET
add_es_library_and_whl(
    ES_LINKABLE_AND_ALL_TARGET es_nn
    OPP_PROTO_TARGET  opgraph_nn
    OUTPUT_PATH       ${CMAKE_BINARY_DIR}/output
)

# 使用多个TARGET
add_executable(my_inference_app main.cpp)
target_link_libraries(my_inference_app PRIVATE
    es_math
    es_nn
)

add_es_library_and_whl(
    ES_LINKABLE_AND_ALL_TARGET es_math
    OPP_PROTO_TARGET  opgraph_math
    OUTPUT_PATH       ${CMAKE_BINARY_DIR}/output  # 共享路径
)

add_es_library_and_whl(
    ES_LINKABLE_AND_ALL_TARGET es_nn
    OPP_PROTO_TARGET  opgraph_nn
    OUTPUT_PATH       ${CMAKE_BINARY_DIR}/output  # 共享路径
)
