CMake在Visual Studio下保持目录结构
原理
主要通过CMAKE自带函数source_group来设定。
需要把add_executable()函数进行封装，包裹一层source_group()的处理
例子
现有目录结构
hello/include/hello.hpp
hello/src/hello.cpp
hello/CMakeLists.txt
编写CMakeLists.txt
cmake_minimum_required(VERSION 3.1)
project(hello)
function(assign_source_group)
foreach(_source IN ITEMS ${ARGN})
if (IS_ABSOLUTE "${_source}")
file(RELATIVE_PATH _source_rel "${CMAKE_CURRENT_SOURCE_DIR}" "${_source}")
else()
set(_source_rel "${_source}")
endif()
get_filename_component(_source_path "${_source_rel}" PATH)
string(REPLACE "/" "\" _source_path_msvc "${_source_path}")
source_group("${_source_path_msvc}" FILES "${_source}")
endforeach()
endfunction(assign_source_group)
function(my_add_executable)
foreach(_source IN ITEMS ${ARGN})
assign_source_group(${_source})
endforeach()
add_executable(${ARGV})
endfunction(my_add_executable)
my_add_executable(hello include/hello.hpp src/hello.cpp)
执行编译
cd hello
mkdir build
cd build
cmake .. -G "Visual Studio 14 Win64"
cmake --build .
打开hello/build/hello.sln看看，是不是好了！
