CMake Project in Visual Studio 2019

小结

在Visual Studio 2019里使用CMake的工程碰到一些问题:
找不到Boost库
找不到OpenSSL库
进行了解决,并测试成功。

问题和解决

在Visual Studio 2019里使用CMake的工程可以参考微软的官方文档:
CMake projects in Visual Studio

找不到Boost库

比较觉的问题是找不到Boost的库文件,例如找不到libboost_regex-vc142-mt-gd-x64-1_70.lib,大体上有以下一些解决办法:

编辑CmakeLists.txt文件
编辑CmakeLists.txt文件加入路径,例如:

SET(BOOST_LIBRARYDIR "C:/boost_1_70_0/stage/lib")
SET(BOOST_LIBRARY_DIR "C:/boost_1_70_0/stage/lib")
SET(BOOST_INCLUDEDIR "C:/boost_1_70_0")
SET(BOOST_INCLUDE_DIR "C:/boost_1_70_0")
set(BOOST_ROOT "C:/boost_1_70_0")
SET(BOOST_lib "C:/boost_1_70_0/stage/lib")

以下设置可以解决很多问题:

add_definitions( -DBOOST_ALL_NO_LIB )
add_definitions( -DBOOST_SYSTEM_NO_DEPRECATED )
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED      ON)
set(Boost_USE_STATIC_RUNTIME    OFF)
set(Boost_DEBUG      ON)

设置Visual Studio 2019

在Visual Studio 2019中Project –> CMake Settings for 'Your Porject Name'可以进行各种Cmake Settings

Cmake command arguments加入:
-DBoost_DEBUG=ON -DBOOST_INCLUDEDIR="C:/boost_1_70_0/libs" -DBOOST_LIBRARYDIR="C:/boost_1_70_0/stage/lib"

设置Windows环境变量
可以设置一些Windows的环境变量,如下:

Environment Vairables –> System variables添加:
BOOST_INCLUDEDIR –> C:\boost_1_70_0\libs
BOOST_LIBRARYDIR –> C:\boost_1_70_0\stage\lib
BOOST_ROOT –> C:\ROS\boost_1_70_0

或者添加到Path环境变量中。

找不到OpenSSL库

OpenSSL下载源码需要编译,这里直接安装OpenSSL,下载并安装 了Win64OpenSSL-3_0_5.msi

Environment Vairables –> System variables添加:
OPENSSL_CRYPTO_LIBRARY –> C:\Program Files\OpenSSL-Win64\lib
OPENSSL_INCLUDE_DIR –> C:\Program Files\OpenSSL-Win64\include
OPENSSL_LIBRARIES –> C:\Program Files\OpenSSL-Win64\lib
OPENSSL_ROOT_DIR –> C:\Program Files\OpenSSL-Win64
