【中文标题】为 gtk、gtkmm 和 opencv 更正 CMakeLists.txt 文件

【英文标题】：Correct CMakeLists.txt file for gtk, gtkmm and opencv

【问题描述】：

我正在尝试编译一个使用 gtkmm 和 opencv 的 GTK2 程序。我用命令行 g++ 试过了：

g++ main.cpp -o bla `pkg-config --cflags --libs gtkmm-2.4 opencv`

这会引发与下面的输出相同的错误。

我用 cmake 和下面的 CMakeLists.txt 文件尝试过：

project (gtk-test)
cmake_minimum_required (VERSION 2.4)

find_package (PkgConfig REQUIRED)
pkg_check_modules (GTK2 REQUIRED gtk+-2.0)

include_directories ($GTK2_INCLUDE_DIRS)
link_directories ($GTK2_LIBRARY_DIRS)
add_executable (gtk-test main.c)
add_definitions ($GTK2_CFLAGS_OTHER)
target_link_libraries (gtk-test $GTK2_LIBRARIES)

cmake 。 && 制作：

CMake Warning (dev) at CMakeLists.txt:6 (link_directories):
This command specifies the relative path

   $GTKMM_LIBRARY_DIRS

  as a link directory.

  Policy CMP0015 is not set: link_directories() treats paths relative to the
  source dir.  Run "cmake --help-policy CMP0015" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.
This warning is for project developers.  Use -Wno-dev to suppress it.

等等。我在这里想念什么？任何帮助将不胜感激。如何一次性编译 Gtk/gtkmm 和 opencv？

【问题讨论】：

你尝试谷歌错误信息吗？ Here 他们说你需要启用 C++11。

我用谷歌搜索了很多次:-) 但是我没有用谷歌搜索 C++11 错误。这似乎很有帮助，谢谢，我会试试看。

【参考方案1】：

GTKmm 和 GTK 是两个不同的东西。 GTKmm 是 GTK 的 C++ 绑定，因此 GTKmm 依赖于 GTK 库。

对于 CMake 和 GTKmm，只需查看using CMake with GTKmm 上的官方 wiki 页面。
