Eigen3 | eigen -

I'm using CLion as my IDE for C++ development and I'm trying to get Eigen included.

How do I do this? I've downloaded and unzipped Eigen and placed it in C:/ (Which I've read online is the path where CMake looks for libs when you use find_library())

In the CMakeLists.txt I've added

Currently I am building an image for the IMX8M-Plus Board with a Yocto-Project on Windows using WSL2.

I enlarged the standard size of the WSL2 image from 250G to 400G, as this project gets to around 270G.

The initialization process is identical with the one proposed from compulab -> Github-Link

During the building process the do_configure step of tensorflow lite fails.

The log of the bitbake process that fails is as following:

I need to make a graphical window with a Qt widget that allows to represent inside it a point cloud that I have previously loaded using the PLC library.

Here's what I have so far that doesn't work (I based it on tutorials and this answer).

I'm using:

• Ubuntu 20.04
• Qt Creator 5.15
• VTK 9.1
• PCL 1.12

The reason I am using QVTKOpenGLStereoWidget is that as far as I read both QVTKOpenGLWidget and QVTKWidget are no longer available or will be discontinued in future releases.

I have just started using conan from my cmake files to download and build dependencies - very convenient. I have tried using it also for Boost, but the default conanfile for boost does not seem to build boost python which I need. My current setup looks like:

Essentially I have defined a class to handle my callbacks, with the declarations and definitions split between a header and source file. However I am having troubles compiling a file which then uses said callback (despite me attempted to link the object file of the callback), specifically I get a linker error:

I have simple C++ project that is organized like this:

I am not good with CMake, and I cannot find good explanations about how to use its FetchContent functionality. Indeed, most repositories seem to require different treatment, and the rules of such treatment defy my comprehension.

That said, here is my problem. I would like to use CppADCodeGen in my project using CMake FetchContent. Here is my code:

I am trying to compile a program with MKL support in Eigen3. However, I keep running into

Have a straightforward problem with testing out some Eigen functionality. I'm creating a constructor that takes 3 Eigen::Vector by reference. When I construct those 3 in my main and call the Interp object (the class I created) constructor, I get that the constructor desires Eigen::MatrixXd (see the compile error at the bottom of this question). My code is shown below. I haven't added much functionality yet so I'd say it's a pretty bare-bone problem but I can't find a solution myself.
