我正在转换一个项目以停止使用Visual Studio 项目文件并切换到使用cmake.

该项目已经有几年的历史了,并且使用了位于代码树之外的自定义预编译外部库:

src/
    ... 源码树 ...
externalLibs/
    Python27/
        include/
            ... 头文件 ...
        libs /
            python27.lib
            python27_d.lib
cmake/
    Modules/
        FindPython2.cmake

我所做的是添加目录cmake/Modules,并在其中添加文件 FindPython2.cmake

然后,我创建了CMakeLists.txt项目组件之一:

cmake_minimum_required( VERSION 3.17 )
project( ConnectorTests CXX )

include( ../../../../../global.cmake )

set( CMAKE_MODULE_PATH "${ROOT_PATH}/cmake/Modules" ${CMAKE_MODULE_PATH} )

message( "CMAKE_MODULE_PATH:" "${CMAKE_MODULE_PATH}" )

find_package( Python2 REQUIRED )

add_executable( ConnectorTests pch.h pch.cpp Tests.cpp )

target_include_directories( ConnectorTests PRIVATE
  ../../Connector
  ../../MtoUtils
  "${Python2_INCLUDE_DIRS}"
)

target_link_libraries( ConnectorTests PRIVATE Python2 )

以上只是相关部分的摘录。

include( ../../../../../global.cmake我在路径定义中包含了一个全局变量set( CMAKE_MODULE_PATH "${ROOT_PATH}/cmake/Modules"$ {CMAKE_MODULE_PATH} )find_package( Python2 REQUIRED )

我放了一个message( )看看一切是否正常,它向我展示了我的期望:

CMAKE_MODULE_PATH: E:/cmake/Modules

我的FindPython2.cmake模块是这样的:

add_library( Python2 SHARED IMPORTED )

if( WIN32 )
  set_target_properties( Python2 PROPERTIES IMPORTED_LOCATION_RELEASE "${ROOT_PATH}/externalLibs/Python27/libs/python27.lib" )
  set_target_properties( Python2 PROPERTIES IMPORTED_LOCATION_DEBUG "${ROOT_PATH}/externalLibs/Python27/libs/python27_d.lib" )
endif( )

set( Python2_FOUND ON )
set( Python2_Development_FOUND ON )
set( Python2_Development.Module_FOUND ON )
set( Python2_Development.Embed_FOUND ON )
set( Python2_INCLUDE_DIRS "${ROOT_PATH}/externalLibs/Python27/include" )

我生成项目没有问题:

 cmake -B build -T v141, host = x86 -A win32

但是在编译时:

 cmake --build build

LINK : 致命错误 LNK1104: no se puede abrir el archivo 'Python2-NOTFOUND.obj' [E:\Desarrollo\PATH\build\Test\ConnectorTests\ConnectorTests.vcxproj]

我在用着:

cmake --version
cmake 版本 3.17.20032601-MSVC_2

  • 我究竟做错了什么 ?
  • 我该如何解决?
