Freeglut-3.0.0是使用cmake（MinGW makefile）和mingw构建的，然后使用mingw32-make installto 成功安装C:/Program Files (x86)/freeglut。

我的CMakeLists.txt是：

    cmake_minimum_required(VERSION 3.7)

    project(math_tests)

    set(TESTS_SOURCES tests.cpp gl_core_3_3.c)
    set(CMAKE_CXX_STANDARD 11)

    # GLUT
    find_package(GLUT REQUIRED)
    include_directories(${GLUT_INCLUDE_DIR})
    if(NOT GLUT_FOUND)
        message(ERROR "GLUT not found!")
    endif(NOT GLUT_FOUND)

    # OpenGL
    find_package(OpenGL REQUIRED)
    include_directories(${OpenGL_INCLUDE_DIRS})
    link_directories(${OpenGL_LIBRARY_DIRS})
    add_definitions(${OpenGL_DEFINITIONS})
    if(NOT OPENGL_FOUND)
        message(ERROR "OPENGL not found!")
    endif(NOT OPENGL_FOUND)

    add_executable(tests ${TESTS_SOURCES})
    target_link_libraries(tests math ${GLUT_LIBRARIES} ${OPENGL_LIBRARIES})

现在，CMake打印错误： Could NOT find GLUT (missing: GLUT_glut_LIBRARY).

我不知道自己在做什么错。
