Question

在我的CMakeLists.txt中，我有第33行：

link_directories (${QT_LIBRARIES})

${QT_LIBRARIES}扩展为：

optimized;C:/QtSDK/Desktop/Qt/4.8.1/msvc2010/lib/QtOpenGL4.lib;debug;C:/QtSDK/Desktop/Qt/4.8.1/msvc2010/lib/QtOpenGLd4.lib

更新CMake 2.8.10.1后，我收到以下警告：

CMake Warning (dev) at CMakeLists.txt:33 (link_directories):
  This command specifies the relative path

    optimized

  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.

但是，正如您所看到的，${QT_LIBRARIES} 不包含相对路径。在我看来，CMP0015政策与此无关。

是我的错误在某处还是在CMake中有错误？

Answer 1

${QT_LIBRARIES}是库的列表，不是库路径。它旨在用于target_link_libraries()。将您的第33行替换为：

targe_link_libraries(yourTargetName ${QT_LIBRARIES})

请注意，不建议使用link_directories()以支持target_link_libraries()中的完整路径。

CMake 2.8.10.1将debug / optimized视为相对目录
