gtk、gtkmm和opencv的正确CMakeLists.txt文件

Question

我正在尝试编译一个使用gtkmm和opencv的GTK2程序。我使用命令行g++进行了尝试：

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

这将抛出与下面的输出相同的错误。

我用cmake和下面的CMakeLists.txt文件尝试了一下：

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。&&生成：

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.

诸若此类。这里我漏掉了什么？任何帮助都将永远受到感谢。如何一次性编译Gtk/gtkmm和opencv？

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，只需看看using CMake with GTKmm上的官方维基页面即可。
