pushd命令用于更改新目录并(或)压栈,或者把栈里的某个目录推到栈顶。
echo %my_install_dir%
gRPC_ABSL_PROVIDER is "module" but ABSL_ROOT_DIR is wrong
第三方库没有准备好
linux如何安装这些？
$ sudo apt install -y build-essential autoconf libtool pkg-config
全下载再试,成功了。
cmake -DgRPC_INSTALL=ON -DgRPC_BUILD_TESTS=OFF -DCMAKE_INSTALL_PREFIX=$MY_INSTALL_DIR ../..
生成了vs工程。
下载git子模块最快：
git clone --recurse-submodules -b v1.41.0 https://github.com/grpc/grpc
最终：新建一个git项目，一个一个的加子模块，先下载再复制到项目下，OK，终于全部下载下来了。
过程，别试：
主库用gitee同步，可以快速下载。.gitsubmodule中子库（第三方库）怎么一下全部下载呢？
怎么命令不顶用？
git submodule update --recursive
可能是因为我是zip下载的，git clone 下载后是可以用的。
但是子模块下载特别慢。我把所有子模块全同步到gitee
再改.submodules里所有链接到gitee (大家如果用，最好先进我的gitee，每个都点下同步到最新)

//新建一个分支 git branch gitee //本地修改.gitmodules 地址全改为gitee //提交 git commit 'from gitee OK' //下载子模块 git submodule update --init --recursive
不行。git中submodule修改子模块的git地址不起作用，还是原来的地址。
新建一个git项目，一个一个的加，OK，终于全部下载下来了。
