Question

在make install期间制作CMake副本文件很简单：

install(TARGETS foo DESTINATION lib)
install(DIRECTORY Include/ DESTINATION include)

但是有可能编写make symlink来制作符号链接而不是复制文件吗？如果是这样，怎么样？

Answer 1

编写创建所需符号链接的CMake脚本：

<强> symlink_include_dir.cmake.in ：

execute_process(COMMAND cmake -E create_symlink
    "@CMAKE_SOURCE_DIR@/include" # Old name
    "@CMAKE_INSTALL_PREFIX@/include" # New name
)

在CMakeLists.txt中配置此脚本以针对实际源和安装路径进行调整，并从install(SCRIPT)调用它：

<强>的CMakeLists.txt ：

# This will copy original script with @variable@ replaced with variable's value.
configure_file("symlink_include_dir.cmake.in" "symlink_include_dir.cmake"
   @ONLY)

# Tell CMake to use the script at install stage
install(SCRIPT "${CMAKE_CURRENT_BINARY_DIR}/symlink_include_dir.cmake")

Answer 2

好的，在阅读了建议的答案并做了几次尝试之后，我设法写了代码：

add_custom_target(symlink
    ${CMAKE_COMMAND} -E create_symlink ${CMAKE_ARCHIVE_OUTPUT_DIRECTORY}/libfoo.a ${CMAKE_INSTALL_PREFIX}/lib/libfoo.a
    COMMAND ${CMAKE_COMMAND} -E create_symlink ${CMAKE_SOURCE_DIR}/Include ${CMAKE_INSTALL_PREFIX}/include)

CMake：符号链接文件，而不是在安装期间复制它们
