2、安装libssh2
vcpkg install libssh2:x64-windows
1、cmakelist.txt
SET(CMAKE_TOOLCHAIN_FILE "C:/Users/oceanstar/vcpkg/win/vcpkg/scripts/buildsystems/vcpkg.cmake")
find_package(Libssh2 CONFIG REQUIRED)
target_link_libraries(cmake_test PRIVATE Libssh2::libssh2)
Add the installation prefix of "Libssh2" to CMAKE_PREFIX_PATH or set
"Libssh2_DIR" to a directory containing one of the above files. If
"Libssh2" provides a separate development package or SDK, be sure it has
been installed.
.\vcpkg integrate install
或者:
# CMakeList.txt: cmake_test 的 CMake 项目,在此处包括源代码并定义 # 项目特定的逻辑。 # cmake_minimum_required (VERSION 3.8) # SET(CMAKE_TOOLCHAIN_FILE "C:/Users/oceanstar/vcpkg/win/vcpkg/scripts/buildsystems/vcpkg.cmake") include_directories("C:/Users/oceanstar/vcpkg/win/vcpkg/installed/x64-windows/include") link_directories("C:/Users/oceanstar/vcpkg/win/vcpkg/installed/x64-windows/lib") # 将源代码添加到此项目的可执行文件。 add_executable (cmake_test "cmake_test.cpp" "cmake_test.h") # TODO: 如有需要,请添加测试并安装目标。 target_link_libraries(cmake_test PRIVATE libssh2.lib)

#Windows库编译# libssh2
Windows VS2015 编译 libssh2 1.7.0
可以使用命令行方式生成vc项目:
编写好CMakelists.txt
执行cmake命令:
cmake …"-DCMAKE_TOOLCHAIN_FILE=D:\vcpkg-master\vcpkg\scripts\buildsystems\vcpkg.cmake" -G"Visual Studio 14"
