c - CMake 没有制作 makefile

Question

我正在尝试在 Windows 中创建动态库。我按照dart-ffi中的说明进行操作。

这是我的CMakelists.txt

cmake_minimum_required(VERSION 3.20.2 FATAL_ERROR)
project(libgit VERSION 1.0.0 LANGUAGES C)
add_library(libgit SHARED git2.h)

set_target_properties(libgit PROPERTIES
    PUBLIC_HEADER git2dart.h
    VERSION {PROJECT_VERSION}
    SOVERSION 1
    LINKER_LANGUAGE C
    OUTPUT_NAME "git2dart"
)

您可以使用 in 克隆 repogh repo clone nivekithan/git2dart

您将CMakeFiles.txt在目录中找到libgit2。

如果我是cmake .从这个目录运行的，那么我会收到这条消息

 Building for: Visual Studio 16 2019
-- Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.21376.

-- Detecting C compile features

-- Generating done
-- Build files have been written to: C:/Users/nivek/Documents/work/git2dart/libgit2

但是如果我要跑步，make我会收到这条消息

make: *** No targets specified and no makefile found.  Stop.

谢谢您的帮助

cmake /?您将看到可用生成器的列表。目前您为 Visual Studio 生成的不是make. 我个人更喜欢ninja
