CMake 正在删除项目 c

Question

我使用 QtCreator 在 Windows 上工作。我尝试使用 freeglut/opengl2 所有库都已正确构建和安装但对所有 glut 组件的未定义引用肯定是由于：目标可能仅链接到库。 CMake 正在删除该项目。

这是我的 CMakelists.txt

 project(Projet_AIN CXX)
cmake_minimum_required(VERSION 2.8)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 ")
find_package(GLUT   REQUIRED)
find_package(GLEW   REQUIRED)
find_package(OpenGL REQUIRED)

include_directories(${GLEW_INCLUDE_DIR}
                    ${GLUT_INCLUDE_DIR}
                    ${OpenGL_INCLUDE_DIR})

link_directories(${GLEW_LIBRARIES_DIR}
                 ${GLUT_LIBRARY_DIR}
                 ${OpenGL_LIBRARY_DIR})

add_definitions(${OpenGL_DEFINITIONS}
                ${GLEW_DEFINITIONS}
                ${GLUT_DEFINITIONS})

set(EXECUTABLE_OUTPUT_PATH bin/${CMAKE_BUILD_TYPE})
file(
    GLOB
    SOURCE_FILES
    include/*.hpp
    src/*.cpp
)

add_executable(
        ${PROJECT_NAME}
        ${SOURCE_FILES}
)
target_link_libraries(${PROJECT_NAME}
                  ${OPENGL_LIBRARY}
                  ${GLEW_LIBRARY}
                  ${GLUT_LIBRARY}
                  )

CMake 输出：

Answer 1

从根本上说，要摆脱 Targets may link only to libraries.CMake is dropping the item. 错误，您需要尝试仅链接到 lib 的路径而不是 lib 目录

例如：

如果您指定：

 FREETYPE_LIBRARY_REL = H:\OgreSDK_vc9_v1-7-1\lib\release

您需要指定 .lib 的路径：

 FREETYPE_LIBRARY_REL = H:\OgreSDK_vc9_v1-7-1\lib\release\freetype.lib
