libigl，GLEW，GLFW和Eigen在CLion，Windows 10上.链接器错误



我确定我错过了一些微不足道的东西，但我无法确定是什么。

我正在使用 CLion 构建一个包含四个外部库的项目。我正在尝试链接Eigen，GLEW，GLFW和libigl。我在VS 2015中使用VC ++编译器。

这是我的cmake文件的一个迭代：

cmake_minimum_required(VERSION 3.9)
project(Lab1)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_CXX_STANDARD 17)
add_executable(Lab1 main.cpp)
include_directories(external/libigl/include)
include_directories(external/glfw/include/)
include_directories(external/eigen-git-mirror/)
include_directories(external/glew_2_1_0/include)
INCLUDE_DIRECTORIES(external/glew_2_1_0/lib/Release/x64)
link_libraries(external/glew_2_1_0/lib/Release/x64)

我已将 glew 库(32 位和 64 位)添加到 VC++ 中各自的文件夹中。我还将 glew32.dll 文件添加到(64 位和 32 位)到系统文件夹中的相应文件夹中。如果我定义在我的 Cmake 文件中查找它们的位置，我认为我不需要这样做，但我不完全确定。

这是我在CLion中的文件夹结构： CLion 文件夹结构。

以下是 main.cpp 包含的内容，以防万一：

#include <igl/readOFF.h>
#include <igl/viewer/Viewer.h>
Eigen::MatrixXd V;
Eigen::MatrixXi F;
int main(int argc, char *argv[])
{
// Load a mesh in OFF format
igl::readOFF("bunny.off", V, F);
// Plot the mesh
igl::viewer::Viewer viewer;
viewer.data.set_mesh(V, F);
viewer.launch();
}

这些是我得到的链接器错误。

感谢您的帮助。

编辑：齐瓦列夫帮助我解决了明显的错误。将所有内容也更改为 32 位。减少到 47 个未解决的外部。工作后将更新。 当前 Cmake：

cmake_minimum_required(VERSION 3.9)
project(Lab1)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_CXX_STANDARD 17)
link_libraries(../external/glew_2_1_0/lib/Release/Win32/glew32s)

add_executable(Lab1 main.cpp)

include_directories(external/libigl/include)
include_directories(external/glfw/include/)
include_directories(external/eigen-git-mirror/)
include_directories(external/glew_2_1_0/include)

编辑：解决了一切正常！缺少一些库。决定在本地链接它们。这是遇到这种情况的下一个倾倒灵魂的cmake：

cmake_minimum_required(VERSION 3.9)
project(Lab1)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_CXX_STANDARD 17)
link_libraries(../external/glew_2_1_0/lib/Release/Win32/glew32s)
link_libraries(../external/glfw/lib-vc2015/glfw3)
link_libraries(../external/openGL/OPENGL32)
link_libraries(../external/openGL/glut32)
link_libraries(../external/openGL/glu32)
find_package(OpenGL REQUIRED)
include_directories( ${OPENGL_INCLUDE_DIRS})
#target_link_libraries(${PROJECTNAME} ${OPENGL_LIBRARIES})


add_executable(Lab1 main.cpp)

include_directories(external/libigl/include)
include_directories(external/glfw/include/)
include_directories(external/eigen-git-mirror/)
include_directories(external/glew_2_1_0/include)

感谢您的帮助！

命令link_libraries只影响更远的目标，所以应该在调用add_executable之前发出。

此外，link_libraries接受库文件，而不是包含它们的目录。
