Question

我有一个简单的项目，正在Windows for Linux上交叉编译。我使用CPack将项目成功构建，安装并打包到tarball中。

现在，我想将跨工具链中的运行时依赖项（libc，libcrypto，ipbthread等）添加到tarball中。

乍一看，似乎include(InstallRequiredSystemLibraries)应该可以解决问题。但是，我似乎无法将RequiredSystemLibraries复制到输出文件夹。另外，下面的跟踪消息始终返回空CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS。

使用跨工具链时，include(InstallRequiredSystemLibraries)机制如何工作？这种机制如何确定我的Linux应用程序的运行时依赖关系？

这是我项目的CMakeLists.txt：

cmake_minimum_required(VERSION 3.12) 
project(Test_App CXX) 
[...]
add_subdirectory(Test_App) 
[...]
# Set packagement management configuration 
set(CPACK_GENERATOR "TBZ2") 
set(CPACK_PACKAGE_NAME "${PROJECT_NAME}") 

include (InstallRequiredSystemLibraries) 
set(CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION "os_dep") 

set(CPACK_SYSTEM_NAME ${CMAKE_SYSTEM_NAME}_${CMAKE_SYSTEM_PROCESSOR}) 
include (CPack) 

message(STATUS "CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS : 
${CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS}")

这是我的跨工具链文件：

cmake_minimum_required(VERSION 3.12) 

set(CMAKE_SYSTEM_NAME Linux) 
set(CMAKE_SYSTEM_PROCESSOR x86_64) 

# specify the cross compiler 
set(tools  c:/cygwin64/opt/x-tools/x86_64-kepware-linux-gnu) 
set(CMAKE_C_COMPILER ${tools}/bin/x86_64-kepware-linux-gnu-gcc.exe) 
set(CMAKE_CXX_COMPILER ${tools}/bin/x86_64-kepware-linux-gnu-g++.exe) 

set(CMAKE_SYSROOT ${tools}/x86_64-kepware-linux-gnu/sysroot) 

# specify the target environment 
set(CMAKE_FIND_ROOT_PATH ${tools}/x86_64-kepware-linux-gnu/sysroot) 

# search for programs in the build host directories 
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) 
# for libraries and headers in the target directories 
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) 
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) 
set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)

这就是我调用CMake的方式：

cmake -G "Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=./cmake/crosstoolchain_x86_64-kepware-linux-gnu.cmake -DCMAKE_INSTALL_PREFIX=<where ever you want> .. 

make 
make install 
cpack
