父CMakeLists.txt覆盖子CMakeLists.txt输出目录选项

Question

我想从项目放置到我的生成输出中的某个目录，但父CMakeLists.txt覆盖输出设置。 父CMakeLists.txt将所有库设置为放置在/ lib目录中。

但是，我的一个库需要放在/ python库中。我在Windows上工作的设置。意思是说，除了我的python特定库之外的所有库都被放置在一个/ lib文件夹中，并且python库被放置到/ python文件夹中。

当我在Linux上构建时出现问题。所有库，包括python特定的库，都被放置到/ lib文件夹中。 FORCE选项什么都不做。

如果我只是建立一个平台，我可以处理任一目录布局。但我真的想要保持跨平台的相同布局。

的CMakeLists.txt如下：

谈到我的意见为答案

我成功测试了以下内容克与MinGW和CMake的3.3.0（I降低你的例子一点集中在输出目录）：

的CMakeLists.txt

cmake_minimum_required(VERSION 2.6) 
project(renderer2d C CXX) 

# TODO: Remove, this is just for testing 
file(WRITE "src/renderer2d.cpp" "int main(void) {}") 
file(WRITE "py_shape/src/py_shape.cpp" "") 

#enable debug symbols by default 
if(CMAKE_BUILD_TYPE STREQUAL "") 
    set(CMAKE_BUILD_TYPE Debug) 
endif() 
#(you can also set on cl: -D CMAKE_BUILD_TYPE=Release) 

#place outside of Debug/Release folders 
#see http://www.cmake.org/Wiki/CMake_Useful_Variables 
set(EXECUTABLE_OUTPUT_PATH "${PROJECT_BINARY_DIR}/bin") 
if(WIN32) 
    set(LIBRARY_OUTPUT_PATH "${EXECUTABLE_OUTPUT_PATH}") 
else() 
    set(LIBRARY_OUTPUT_PATH "${PROJECT_BINARY_DIR}/lib") 
endif() 

#see https://stackoverflow.com/questions/10851247/how-to-activate-c-11-in-cmake 
if (CMAKE_VERSION VERSION_LESS "3.1") 
    if (CMAKE_CXX_COMPILER_ID STREQUAL "GNU") 
    set(CMAKE_CXX_FLAGS "--std=gnu++11 ${CMAKE_CXX_FLAGS}") 
    endif() 
else() 
    set(CMAKE_CXX_STANDARD 11) 
endif() 

#set the source directory 
file(GLOB SOURCES src/*.cpp) 

add_subdirectory(py_shape) 

#define sources and executable 
add_executable(${PROJECT_NAME} ${SOURCES}) 

add_dependencies(${PROJECT_NAME} python_shape) 

py_shape /的CMakeLists.txt

#set file variables 
file(GLOB SOURCE src/*.cpp) 
file(GLOB HEADERS inc/*.hpp) 

#build the library 
add_library(python_shape MODULE ${SOURCE}) 

set_target_properties(python_shape PROPERTIES LIBRARY_OUTPUT_DIRECTORY "${PROJECT_BINARY_DIR}/python") 

#drop "lib" from the library name 
set_target_properties(python_shape PROPERTIES PREFIX "") 

if(WIN32) 
    #set extension to ".pyd" 
    set_target_properties(python_shape PROPERTIES SUFFIX ".pyd") 
endif() 

现在python_shape.pyd创建于python子目录。

我已经修改/删除：

• 在孩子CMakeLists.txt设置..._OUTPUT_DIRECTORY全局变量是没有必要的和/或将无法正常工作
• 增加LIBRARY_OUTPUT_DIRECTORY覆盖输出目录为python_shapeMODULE库目标（另请参阅，例如Custom Directory for CMake Library Output）
• 删除了“by config”设置，因为我认为这是多配置环境（如Visual Studio将不同的配置二进制文件放入e qually命名的子文件夹。
• 在-std=c++11附近增加了一些if陈述。它也仅是在主CMakeLists.txt
• 设置一次，你并不需要“手动”创建输出目录，它们通过使环境更加

对于推理自动创建的，为什么你的第一种方法没有工作，看到我上面的评论。

而且我也不会建议使用file(GLOB ...)收集源文件（见例如Why is cmake file GLOB evil?或CMake/Ninja attempting to compile deleted `.cpp` file）。

替代

与像CMake所有语言/框架有做的事情更多，其中一个方法。

例如你也可以使用POST_BUILD步骤将二进制文件复制到一个公用输出目录：
