Question

我想在Windows 7上使用mingw-4.9，cmake 3.8和Boost 1.63.0编译我的项目。它是一个独立的单元测试项目。它从生产源目录获取文件，测试文件夹模型（替换）中的测试文件也在separete文件夹中。

我不确定我做错了什么。

的CMakeLists.txt

cmake_minimum_required(VERSION 3.8)

project(myProject)

# C, C++ are enabled by default
#enable_language(C CXX)

#definitions
add_definitions(-DWIN32)
add_definitions(-DBOOST_UNITTEST)
add_definitions(-DG_NEWIOSTREAM)

# Configure outputs 
set(ARCHIVE_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/../../output/lib")
set(LIBRARY_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/../../output/lib")
set(RUNTIME_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/../../output/bin")

# Detect operating system
message(STATUS "Operating system is ${CMAKE_SYSTEM_NAME}")
if($(CMAKE_SYSTEM_NAME) STREQUAL "Linux")
    add_definitions(-DSYSTEM_LINUX)
endif()
if($(CMAKE_SYSTEM_NAME) STREQUAL "Windows")
    add_definitions(-DSYSTEM_WINDOWS)
endif()

# Detect host processor 
message (STATUS "The host processor is ${CMAKE_HOST_SYSTEM_PROCESSOR}")

# Settings the Boost Library 
set(Boost_USE_STATIC_LIBS ON) 
set(Boost_USE_MULTITHREADED ON)  
set(Boost_USE_STATIC_RUNTIME OFF) 

# Debuging for cmake
#set(Boost_DEBUG ON)

# Set path to the Boost Library
set(Boost_NO_SYSTEM_PATHS ON)
set(BOOST_ROOT "c:\\dev\\external")
set(BOOST_INCLUDEDIR "C:\\dev\\external\\include")
set(BOOST_LIBRARYDIR "C:\\dev\\external\\lib\\boost")
# At the end find the package, include and link
find_package(Boost 1.63.0 REQUIRED COMPONENTS unit_test_framework regex ) 
include_directories(${Boost_INCLUDE_DIRS})     

# Configure source files for production code
file(GLOB SOURCES ../../sources/*.cpp)

# Configure source files for unit-test code
file(GLOB SOURCES source/*.cpp)
file(GLOB SOURCES source/subs/*.cpp)

# Tell the cmake what needs to be builded
include_directories(${CMAKE_CURRENT_SOURCE_DIR})
add_executable( myProject ${SOURCES} )

# Tell CMake to link it
target_link_libraries( myProject ${Boost_LIBRARIES} )

我项目中的文件结构：

project
 |--sources    <-(production code)
 |--test
 |   |--source     <-(test code)
 |   |   |--subs    <-(substitutions, mockups)
 |   |--CMakeLists.txt 
 |--output
     |--test   <-(cmake generates here)

我使用CMake GUI（v3.8.0 rc4）生成Makefile，然后运行

... output\test>C:\MinGW\bin\mingw32-make.exe

从CMake准备文件的目录，输出如下：

...
[ 87%] Building CXX object CMakeFiles/myProject.dir/source/subs/subs_trace_publ.cpp.obj
[100%] Linking CXX executable myProject.exe
C:/dev/external/lib/boost/libboost_unit_test_framework-mgw49-mt-1_63.a(unit_test_main.o):unit_test_main.cpp:(.text.startup+0x14):

CodeBlocks 16.01项目中的相同代码工作。（Boost，MinGW，相同的路径，设置，版本等。）

如果需要，我可以提供更多信息。

我也欢迎关于CMakeLists.txt的一些提示。

我在一段时间后自己找到了解决方案。

除了文件（..）命令外，一切都很好。对于不同的位置，应使用不同的变量，例如：

# Configure source files for production code
file(GLOB SOURCES_PRODUCTION ../../sources/*.cpp)

# Configure source files for unit-test code
file(GLOB SOURCES_TEST source/*.cpp)
file(GLOB SOURCES_SUBS source/subs/*.cpp)

然后：

add_executable( myProject ${SOURCES_PRODUCTION} ${SOURCES_TEST} ${SOURCES_SUBS})

如果在问题中使用变量SOURCE，则每个分配都会覆盖数据，最后它只包含最后一个路径。

静态链接再次使用cmake进行boost.test，以便在Windows上进行mingw
