Question

我有一个CMake项目，可以在带有g ++的Linux上正常工作。

在Windows（第10版，创建者更新）上，CMake可以正常运行并生成相关文件。

因此，我打开了TestProject.sln解决方案文件，并进行了测试运行，我运行了“本地Windows调试器”，并得到了此错误。

Error   LNK1104 cannot open file 'jsoncpp.lib'

这就是我设置此项目的方式。

.
|-root
|  |- src
|  |- lib
|  |- bin
|  |- app
|  |- include
|  |- extras
|        |- jsoncpp
|-build

我不太确定这里可能出什么问题。

我将jsoncpp添加为子模块。

我做到了

git submodule update --init --recursive

中有一个jsoncpp.lib文件

root\lib\Debug

这是我的CMakeLists.txt

cmake_minimum_required (VERSION 3.13)
project (TestProject)

set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${PROJECT_SOURCE_DIR}/root/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${PROJECT_SOURCE_DIR}/root/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${PROJECT_SOURCE_DIR}/root/bin)

set(SOURCE_DIR ${PROJECT_SOURCE_DIR}/root/src)
set(INCLUDE_DIR ${PROJECT_SOURCE_DIR}/root/include)
set(EXTRAS_DIR ${PROJECT_SOURCE_DIR}/root/extras)
set(PROJECT_MAIN_DIR ${PROJECT_SOURCE_DIR}/root/app)

set(SOURCES
  ${INCLUDE_DIR}/Combinations.hpp  
  ${INCLUDE_DIR}/Lib.hpp  
  ${SOURCE_DIR}/Lib.cpp
  )

add_executable(TestProject ${PROJECT_MAIN_DIR}/Main.cpp ${SOURCES})

add_subdirectory(${EXTRAS_DIR}/jsoncpp jsoncpp)

target_link_libraries(TestProject jsoncpp)

set_target_properties(TestProject PROPERTIES
  CXX_STANDARD_REQUIRED ON
  CXX_STANDARD 17
  CXX_EXTENSIONS OFF
  )

这是CMake的输出

我对Visual Studio不太熟悉，但是看着错误，它说“无法打开”和“无法找到”，所以我的第一想到可能是权限问题。

所以我用Admin Privileges启动了VS，但错误仍然存在。

我认为可能存在一些编译器问题，因此我将nmake.exe用作编译器（在生成nmake makefile之后），但那里也没有运气。

我不确定这是否是链接器问题，因为CMake能够找到并链接jsoncpp库，因此我怀疑CMake在构建Makefile时出错。

我不确定如何调试该问题。
