Can someone please highlight what kind of errors are these?
It is a linker error. There is code somewhere trying to call the functions for the queue class, but there is no queue class linked into the executable.

I'm sure I'm missing something trivial, but I can't put my finger on what.
I'm building a project with four external libraries using CLion. I'm trying to link Eigen, GLEW, GLFW, and libigl. I'm using the VC++ compiler in VS 2015.
This is one iteration of my cmake file:
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)
I have added the glew libraries (both 32 and 64 bit) to their respective folders in VC++. I've also added the glew32.dll files to (64 and 32 bit) to their respective folders in the system folders. I don't think I need to do this if I define where to look for them in my Cmake file, but I'm not entirely sure.
This is my folder structure in CLion:
CLion folder structure.
Here's what main.cpp contains in case it matters:
#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();
}
These are the linker errors I get.

Thanks for the help.
EDIT:
Tsyvarev helped me out with the obvious errors. Changed everything to 32-bit too. Down to 47 unresolved externals. Will update once it's working.
Current Cmake:
cmake_minimum_required(VERSION 3.9)
project(Lab1)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_CXX_STANDARD 17)

include_directories(external/libigl/include)
include_directories(external/glfw/include/)
include_directories(external/eigen-git-mirror/)
include_directories(external/glew_2_1_0/include)
EDIT: SOLVED It all works! Was missing some libraries. Decided to link them locally. Here's the cmake for the next pour soul that comes across this:

Thanks for the help!
Command link_libraries affects only on futher targets, so it should be issued before add_executable call.
Also, link_libraries accepts library files, not a directory with them.
I'm trying to compile the zeromq sources and I have the following error:
I'm using Visual studio 2013 update 4 / windows 7 x64
First of all I compile the libsodium library satisfactorily.
Then I link the libsodium header files directory path to additional dependencies and libsodium.lib to additional library directories. I also specify the name of library in additional dependencies.
I try to compile it under win32 architecture and x64 architecture but I get the same errors.
I know that a __imp prefix is used as a bridge to the function that I want to use so if I linked the libraries appropiately why do I get this error?

Thanks in advance.
You're probably compiling libsodium in a static way.
Try to compile it dinamically and link it again.
Such errors are also able to occur when you have a wrong set calling convention at your project.
I am trying to build OSGEarth using CMAKE and Visual studio 2013
I first downloaded Open Scene Graph 3.2 and the prebuild dependencies (small package) from this page. I generated the visual studio 2013 project and build/installed Open Scene Graph without much problem
After that, I downloaded the source of osgearth 2.5 and generated the Visual Studio 2013 project, using the same dependencies as for Open Scene Graph (I don't want to use the optional dependencies for the first build) and when I try to build the osgEarth project, I got the following error at the linking step :

The only think I was able to find is that all the missing method seems to be deprecated ODBC method, like this one
For additional information, the project got a reference to odbc32.lib in its inherited values.
Okay, stupid question... the odbc's dependencies were in the inherited values... but the checkbox indicated to the build process to use these dependencies was not checked. Once it was done, everything is good... I think I need either a coffee or a very big smack on the head...

I am a complete newbie in cpp and I would appreciate any help!
Thank you!
In the code it is compiling when i use float datatypes then when changing the float to double in typedef there are above linking errors.

I already saw other posts regarding this error but was unable resolve it using the workarounds mentioned in the answers. Thanking you
