CMake7-install部署项目6：install Exports【用于find_package导入库】

一、find_package

二、install export

install(EXPORT <export-name> DESTINATION <dir>
        [NAMESPACE <namespace>] [FILE <name>.cmake]
        [PERMISSIONS permissions...]
        [CONFIGURATIONS [Debug|Release|...]
        [CXX_MODULES_DIRECTORY <directory>]
        [EXPORT_LINK_INTERFACE_LIBRARIES]
        [COMPONENT <component>]
        [EXCLUDE_FROM_ALL])
install(EXPORT_ANDROID_MK <export-name> DESTINATION <dir> [...])

# 支持find_package
# 生成并安装配置文件 xlogConfig.cmake
instaLl(EXPORT ${PROJECT_NAME} FILE ${PROJECT_NAME}Config.cmake
    DESTINATION lib/config/${PROJECT_NAME}-${version}
)

三、代码

1、安装库【export_my_package】

# 506export_my_package/CMakeLists.txt
cmake_minimum_required(VERSION 3.22)

project(export_my_package)
# cmake -S . -B build -DCMAKE_INSTALL_PREFIX=/home/xcj/xcpp
file(WRITE include/slib.h "void SLib();"
