使用 cmake 安裝目標依賴項

Question

我有一個應該安裝靜態庫及其所有依賴項的項目。 這些依賴項之一是boost 。

我有類似以下的東西，但它不起作用：

cmake_minimum_required(VERSION 3.9.0)

project(install_test)

find_package(Boost REQUIRED COMPONENTS system)

set(Boost_USE_STATIC_LIBS TRUE)

add_executable(test src/main.cpp)

target_link_libraries(test Boost::boost)

add_dependencies(test Boost::boost)

install(TARGETS test DESTINATION ${CMAKE_INSTALL_LIBDIR})

install(TARGETS Boost::boost DESTINATION ${CMAKE_INSTALL_LIBDIR})

注意：可以找到boost ，如果我刪除最新的install語句，一切正常。

怎么能做到這一點？

由於安裝很可能發生在同一台機器上（在您的庫將被編譯），並且 Boost 庫已經安裝（因為它可以找到），您應該通過 Config.cmake 文件導出您的庫及其依賴項. 所有依賴項都可以通過find_dependency找到（我認為您不想復制所有 boost 庫）。 它將在與您安裝的庫鏈接時搜索所需的包。

${PROJECT_NAME}Config.cmake.in 文件

@PACKAGE_INIT@

include(CMakeFindDependencyMacro)

find_dependency(glad REQUIRED)
find_dependency(glm REQUIRED)

include("${CMAKE_CURRENT_LIST_DIR}/@targets_export_name@.cmake")

check_required_components(gl_traits)

CMakeLists.txt

#... define here sources and public headers

add_library(${PROJECT_NAME}
    STATIC
        ${PUBLIC_HEADERS}

        ${SOURCES}
    )

set_target_properties(${PROJECT_NAME}
    PROPERTIES

        OUTPUT_NAME ${PROJECT_NAME}
        DEBUG_POSTFIX "_d"

    )

target_link_libraries(${PROJECT_NAME}
    PUBLIC
        Boost::boost
    )

target_include_directories(${PROJECT_NAME}
    PUBLIC
        $<INSTALL_INTERFACE:${INSTALL_INCLUDEDIR}/${PROJECT_NAME}>
        $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include/${PROJECT_NAME}>

    PRIVATE
        $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/src>
    )

set(targets_export_name ${PROJECT_NAME}Targets)
set(project_config ${PROJECT_BINARY_DIR}/${PROJECT_NAME}Config.cmake)
set(version_config ${PROJECT_BINARY_DIR}/${PROJECT_NAME}ConfigVersion.cmake)

include(CMakePackageConfigHelpers)

write_basic_package_version_file(
        ${version_config}
    VERSION
        ${PROJECT_VERSION}
    COMPATIBILITY SameMajorVersion
    )

configure_package_config_file(
        ${PROJECT_SOURCE_DIR}/cmake/${PROJECT_NAME}Config.cmake.in
        ${project_config}
    INSTALL_DESTINATION
        ${INSTALL_CMAKEDIR}
    )

install(TARGETS
        ${PROJECT_NAME}
    EXPORT
        ${targets_export_name}
    ARCHIVE
        DESTINATION ${INSTALL_LIBDIR}
        COMPONENT lib
    LIBRARY
        DESTINATION ${INSTALL_LIBDIR}
        COMPONENT lib
    RUNTIME
        DESTINATION ${INSTALL_BINDIR}
        COMPONENT bin
    )

install(EXPORT
        ${targets_export_name}
    DESTINATION
        ${INSTALL_CMAKEDIR}
    )

install(FILES ${PUBLIC_HEADERS} DESTINATION ${INSTALL_INCLUDEDIR}/${PROJECT_NAME} COMPONENT dev)
install(FILES 
        ${project_config}
        ${version_config}
    DESTINATION
        ${INSTALL_CMAKEDIR}
    )

如果您需要安裝目標文件，請使用$<TARGET_FILE:target_name>
