CMake的 - 在我目前的项目中使用我的其他项目的代码

Question

我有这个结构的C++项目：

-- ProjectFolder 
    -- Project_Prototype1 
    -- Project_Prototype2 

Project_Prototype1有CMakeLists与此内容的文件：

cmake_minimum_required(VERSION 2.8) 
project(Neuromarketing-RF) 
find_package(Boost 1.58.0 REQUIRED COMPONENTS filesystem system) 
include_directories(${Boost_INCLUDE_DIRS} include src/external) 
find_package(OpenCV 3 REQUIRED) 

file(GLOB FACETRACKER_HEADERS "external/FaceTracker/include/FaceTracker/*.h") 
file(GLOB FACETRACKER_SRC "external/FaceTracker/src/lib/*.cc") 
file(GLOB SOURCES "src/*cpp") 

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "bin/") 
add_executable(Neuromarketing-RF ${FACETRACKER_SRC} ${SOURCES}) 
target_link_libraries(Neuromarketing-RF ${OpenCV_LIBS} ${Boost_LIBRARIES}) 
target_compile_features(Neuromarketing-RF PRIVATE cxx_range_for) 

Prototype1是使用外部库称为FaceTracker。

在Prototype2我想从Prototype1访问一个文件，但我不想重新定义Prototype2 CMakeLists（FaceTracker，Boost等）上的Prototype1的所有依赖关系。

如何编写Prototype2 CMakeLists以使用Prototype1而无需手动重新定义所有内容？

这里是我当前的CMakeLists.txt为Prototype2：

cmake_minimum_required (VERSION 2.6) 
project (Neuromarketing-CNN) 
find_package(OpenCV REQUIRED) 
find_package(Boost 1.58.0 REQUIRED COMPONENTS filesystem system) 

add_subdirectory("../Neuromarketing-RF" "../Neuromarketing-RF/bin") 

file (GLOB NM_RF_SRC "../Neuromarketing-RF/src/*.cpp") 
include_directories(include ../Neuromarketing-RF/include ${Boost_INCLUDE_DIRS}) 
file(GLOB SOURCES "src/*.cpp") 
add_executable (bin/Neuromarketing-CNN ${SOURCES} ${NM_RF_SRC}) 
target_link_libraries(bin/Neuromarketing-CNN ${OpenCV_LIBS} ${Boost_LIBRARIES}) 
target_compile_features(bin/Neuromarketing-CNN PRIVATE cxx_range_for) 

Answer 1

最简单的方法是创建一个包含所有的依赖共同文件既CMakeList.txt文件，并使用包括（）。比如有一个文件名ProjectFolder包含相关find_package（/我-includes.cmake）语句，并在这两个CMakeList.txt文件添加一行在包含文件中定义

include ("../my-includes.cmake") 

一切可用包含文件。
