cmake/modules/Findasio.cmake:11 处的 CMake 错误 - 无法找到 ASIO 依赖项

Question

我正在尝试在 visual studio 2015 项目中使用 restbed framework。

我克隆了 restbed 存储库：https://github.com/Corvusoft/restbed.git

为了创建一个 Visual studio 项目文件，我使用的是当前 cmake 3.8.1 版本

现在，当尝试使用 cmake 配置 restbed 时，我收到此错误：

  Copyright 2013-2017, Corvusoft Ltd, All Rights Reserved.
CMake Error at cmake/modules/Findasio.cmake:11 (message):
  Failed to locate ASIO dependency.
Call Stack (most recent call first):
  CMakeLists.txt:31 (find_package)

有没有办法解决这个 Asio 问题？

现在我正在尝试编译 Boost library 以查看在哪里可以找到并将这些 Asio 依赖项添加到 Cmake。

CMakeLists.txt 休息床文件的内容：

line
26   #
27   # Dependencies
28   #
29   set( CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${PROJECT_SOURCE_DIR}/cmake/modules" )
30 
31   find_package( asio REQUIRED )
32   include_directories( SYSTEM ${asio_INCLUDE} )

CMake（配置）输出：

The CXX compiler identification is MSVC 19.0.24215.1
Check for working CXX compiler: F:/Program Files (x86)/Microsoft Visual 
Studio 14.0/VC/bin/x86_amd64/cl.exe

Answer 1

Asio（不要与 boost asio 混淆）在 restbed 存储库中 included 作为 Git 子模块。 CMake 应该在第一个运行时自动找到 Asio 的 headers。克隆项目后，您可能忘记了运行 git submodule init 和 git submodule update。运行您克隆 restbed 的目录中的那些命令，并且构建应该开始工作。

如果您确实需要将 restbed 指向特定的 asio 安装，根据 this file，只需将 CMake 变量 asio_INCLUDE 设置为包含 asio.hpp.

的目录

Answer 2

您是否遵循了自述文件中的说明？

git clone --recursive https://github.com/corvusoft/restbed.git
mkdir restbed/build
cd restbed/build
cmake [-DBUILD_TESTS=YES] [-DBUILD_EXAMPLES=YES] [-DBUILD_SSL=NO] [-DBUILD_SHARED=YES] [-DCMAKE_INSTALL_PREFIX=/output-directory] ..
make [-j CPU_CORES+1] install
make test

Answer 3

您收到此错误是因为未安装 asio 库。

从 https://think-async.com/Asio/

下载、构建和安装 asio 库

./configure --without-boost
make
sudo make install

然后下载restbed并构建

git clone https://github.com/Corvusoft/restbed.git
mkdir restbed/build
cd restbed/build
cmake -D BUILD_SSL=OFF -D BUILD_TESTS=OFF -D BUILD_STATIC=ON -D BUILD_SHARED=OFF ..
make
make install
