CMake 找不到 X11 包

Question

我正在尝试运行 verilog 模拟器“verilog-to-routing (vtr)”。构建 vtr 时，我无法启用图形。

将出现一条警告消息：“EasyGL：无法找到所需的 X11 库（在 debian/ubuntu 上尝试sudo apt-get install libx11-dev安装）”。安装 libx11-dev 并不能解决问题。

在文件“vtr-verilog-to-routing-8.0.0/libs/libeasygl/CMakeLists.txt”中，有以下与此相关的行：

#Look for X11, font and cairo libraries 
message(STATUS "EasyGL: UNIX detected, looking for X11 and font libraries")
find_package(Fontconfig)
find_package(X11 COMPONENTS X11 Xft)
find_package(Freetype)
find_package(Cairo)

if(NOT X11_FOUND)
set(FOUND_EASYGL_DEPENDANCIES  false)
message(WARNING "EasyGL: Failed to find required X11 library (on debian/ubuntu try 'sudo apt-get install libx11-dev' to install)")
endif()

当我执行 Makefile 时，出现以下消息：

-- EasyGL: UNIX detected, looking for X11 and font libraries
-- Could NOT find X11 (missing: X11)
CMake Warning at libs/libeasygl/CMakeLists.txt:49 (message):
EasyGL: Failed to find required X11 library (on debian/ubuntu try 'sudo
apt-get install libx11-dev' to install)

-- EasyGL: graphics disabled

libx11-dev 包已安装。

这些是 CMakeCache.txt 文件中的相应行（我只包含 NOTFOUND 路径）：

//Path to a file.
X11_Xpm_INCLUDE_PATH:PATH=X11_Xpm_INCLUDE_PATH-NOTFOUND

//Path to a library.
X11_Xpm_LIB:FILEPATH=X11_Xpm_LIB-NOTFOUND

//Path to a file.
X11_Xss_INCLUDE_PATH:PATH=X11_Xss_INCLUDE_PATH-NOTFOUND

/Path to a library.

//Path to a file.

/Path to a file.
X11_Xxf86misc_INCLUDE_PATH:PATH=X11_Xxf86misc_INCLUDE_PATH-NOTFOUND

//Path to a library.

//Path to a file.
X11_Xxf86vm_INCLUDE_PATH:PATH=X11_Xxf86vm_INCLUDE_PATH-NOTFOUND

//Path to a library.
X11_Xxf86vm_LIB:FILEPATH=X11_Xxf86vm_LIB-NOTFOUND

//Path to a file.
X11_xkbfile_INCLUDE_PATH:PATH=X11_xkbfile_INCLUDE_PATH-NOTFOUND

//Path to a library.
X11_xkbfile_LIB:FILEPATH=X11_xkbfile_LIB-NOTFOUND

当查看目录 usr/inlcude/X11 时，有一个 Xft 目录，看起来它正在创建它。这里，没有任何 X11.h 文件或其他 X11 目录。接下来是目录内容的图片：

我正在使用 Ubuntu 20.04 和 verilog-to-routing 8.0.0。

我在verilog-to-routing github（https://github.com/verilog-to-routing/vtr-verilog-to-routing/issues/1461）中提出了一个问题，但我想这个问题与cmake。

您可能需要安装更多软件包，例如：

apt-get install libxss-dev libxxf86vm-dev libxkbfile-dev libxv-dev

然后再次尝试 cmake 命令。
