【问题描述】：
之前的stackoverflow线程位于here。我的问题发生了很大变化，以至于我认为应该创建一个新线程。我正在使用 CentOS8
我正在努力安装a tool called wave-gui 并且遇到了真正的困难（正如您从上一个帖子中看到的那样）。我当前的问题是当我使用 make 命令时找不到名为 cg_config.h 的文件（我也收到错误 1 和 2）。让我走到这一步的所有故障排除步骤都位于之前的thread。
我已经复制粘贴了下面 make 命令的输出，以及下面输出中提到的“主”目录的内容。
-- Creating program 'wave-gui' with sources:
-- main.cpp
-- app.cpp
-- core.cpp
-- ui.cpp
-- data.cpp
CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as
cmake_minimum_required(VERSION 3.11)
should be added at the top of the file. The version specified may be lower
if you wish to support older CMake versions for this project. For more
information run "cmake --help-policy CMP0000".
This warning is for project developers. Use -Wno-dev to suppress it.

编辑1：从工具中完全删除目录并重新克隆它并运行这些步骤。出现新错误。这次它找不到 SDL2。 （耶进步！）

SDL2 网站说只需使用“sudo yum install SDL2”。当我使用此命令时，我得到以下输出：
Last metadata expiration check: 1:25:41 ago on Mon 26 Oct 2020 09:54:58 AM EDT.
No match for argument: SDL2
Error: Unable to find a match: SDL2
使用相同的命令，但使用 SDL2-devel 得到类似的输出。
我使用“yum search SDL2”得到了这个输出：
Last metadata expiration check: 1:26:51 ago on Mon 26 Oct 2020 09:51:55 AM EDT.
========================================= Summary Matched: SDL2 =========================================

========================================= Summary Matched: SDL2 =========================================

然后我尝试了“sudo yum install baresip-sdl.x86_64”，它给了我这个输出：
Last metadata expiration check: 1:25:25 ago on Mon 26 Oct 2020 09:54:58 AM EDT.
Error:
Problem: conflicting requests
- nothing provides libSDL2-2.0.so.0()(64bit) needed by baresip-sdl-1.0.0-1.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
只是为了好玩，我输入“sudo yum install libSDL-2.0.so.0.so.0”并得到另一个“参数不匹配”
编辑 2：我听从了 yfelion 的建议，安装了 sdl2 glfw3 和 fftw。我现在收到此错误：

我现在正在考虑安装 OpenGL，但正如在上一个线程中所指出的那样，我现在正处于我的头上。我还添加了（应几个人的要求）我正在使用 CentOS8。
编辑 3：我以为我已经安装了 glfw3，但是在安装 OpenGL 之后我得到了这个错误：
mkdir -p build && cd build && cmake .. && make

make: *** [Makefile:2: all] Error 1
当我使用命令“sudo yum install glfw”时，我得到以下输出：

Package glfw-1:3.3-2.el8.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!
编辑 4：安装 glfw-devel 并尝试再次运行 make 命令。这次它比以往任何时候都更进一步（再次！进步！！）。但仍然出现错误。

这似乎是 IMGu 的问题。特别是 -lX----- 东西。我将尝试重新安装 ImGui 看看是否有帮助。也可能重新启动VM。只是看看这是否能解决任何问题。可能不会，但尝试一下也无妨。 也许路径变量或其他东西无法访问它？
【问题讨论】：
-
您应该从顶级项目的目录运行
cmake，而不是从main子目录运行。 -
您使用的是哪个 Linux 发行版？如果您想尝试按文件名安装，您需要提供我认为的完整路径，即
yum install /usr/lib64/libSDL2.so或yum install /usr/lib/libSDL2.so。 -
您可能需要所有这些软件包的 -devel 版本，即 glfw-devel。
