首先,我是CMake的新手。
该项目适用于Windows和Linux平台。
root_project
|─── CMakeLists.txt
|─── Project 1
| |─── build
| | |─── Debug
| | └─── Release
| |─── source
| | |─── CMakeLists.txt
| | └─── include
| |─── resource
| └─── header
└─── Project 2
|─── build
| |─── Debug
| └─── Release
|─── source
| |─── CMakeLists.txt
| └─── include
|─── resource
└─── header
这些文件中的第一个用于根项目,第二个用于“项目1”和“项目2”,因为第二个文件中只有一行不同。

注意:“项目1”是一个库,而“项目2”是可执行文件,“项目2”将基于项目1.将其视为“项目1”是一个引擎而“Project 2”就是游戏。
答案 0 :(得分:1)
我会尝试直接从Developer Command Prompt打开root_project文件夹,按照此处的说明操作: https://blogs.msdn.microsoft.com/vcblog/2016/10/05/cmake-support-in-visual-studio/
cd root_project
devenv .
此内置支持将您的二进制文件转储到%APPDATA%中临时目录下的某个位置,因此我在顶级CMakeLists.txt文件中添加了以下内容以将二进制文件转储到特定文件夹:
# My understanding of what the output types mean. Check CMAKE documentation
# to confirm:
# ARCHIVE: Static & Import Library directory
# LIBRARY: DLL directory (MODULE)
# RUNTIME: DLL directory (SHARED)
# If you use these lines, VS will automatically create Debug and Release dirs
# under the directories you provide.
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY "${CMAKE_CURRENT_LIST_DIR}/../lib")
set (CMAKE_RUNTIME_OUTPUT_DIRECTORY "${CMAKE_CURRENT_LIST_DIR}/../dll")
# In my project I want Debug and Release to clobber each other because
# I am building a DLL that I want to deploy next to an existing exe that
# loads it, so I explicitly point both scenarios to the same place
# (note the "_DEBUG" and "_RELEASE" suffixes to CMAKE_xxx_OUTPUT_DIRECTORY)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY_DEBUG "${CMAKE_CURRENT_LIST_DIR}/../lib")
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY_DEBUG "${CMAKE_CURRENT_LIST_DIR}/../lib")
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_DEBUG "${CMAKE_CURRENT_LIST_DIR}/../dll")
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY_RELEASE "${CMAKE_CURRENT_LIST_DIR}/../lib")
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY_RELEASE "${CMAKE_CURRENT_LIST_DIR}/../lib")
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY_RELEASE "${CMAKE_CURRENT_LIST_DIR}/../dll")
