Like I said, I'm trying to compile VTK (version 5.10.1) using CMake (2.8.12) and QT (4.7.4)
After following the instructions for installing QT using visual studios cmd line, I open up vtk's source, run CMAKE, and attempt to compile the solution file using Visual Studio Pro.
There's a few libraries that aren't compiling, but I'm hoping if someone can explain how to fix one, I can try and fix the others on my own.
When building QVTKWidgetPlugin, I keep getting the following error codes:

I understand that its basically looking for things that aren't defined, but I'm not sure how to fix it. As far as I know this should all run 100% from QT->VTK but I'm having some issues. Thanks in advance!

I am trying to write a User-defined Model in C++ for FLAC in Visual Studio Express 2010 C++. Initially, I am trying to run (debug and build) the built-in Strain-softening Model based on the Mohr-Coulomb criterion (Available in FLAC 8.0) by changing its name only. Once I succeed to do it, I will try to modify it as per my requirement. I am running the code in VS2010. I have already installed SDK7.1, VS2010 SP1, etc. However, I am getting the following error msg:
1>------ Build started: Project: i_ssoft, Configuration: Debug x64 ------

From the error code, it is clear that I need to add some libraries or I need to place the supporting libraries in the same project directory... which I have tried but still, I am getting the error.
I have installed libraries with vcpkg using the correct triplet :
C:\Users\***>vcpkg list libnoise
libnoise:x64-windows 1.0.0 A general-purpose library that generates three-d...
Then I have executed the following command :
C:\Users\***>vcpkg integrate install
Applied user-wide integration for this vcpkg root.
All MSBuild C++ projects can now #include any installed libraries.
Linking will be handled automatically.
Installing new libraries will make them instantly available.
CMake projects should use: "-DCMAKE_TOOLCHAIN_FILE=C:/Windows/vcpkg/scripts/buildsystems/vcpkg.cmake"
But in my Visual Studio 2019 project, with an x64 project, only the headers have been successfully integrated :
#include <noise/noise.h> // The header is found as well as the definition of noise::module::Perlin
int main()
{
noise::module::Perlin noise; // The implementation is not found
}
When trying to compile this, I get :
1>------ Build started: Project: Mayak, Configuration: Debug x64 ------

On a side note, I have looked for the name of the .lib files of the noise library and tried to add them in the Linker > Input properties, it still doesn't work.
What did I do wrong ?
To enable AutoLink, select your current project and go to properties. (Alt-Enter) Make sure you edit the right configuration. Then go to Configuration Properties -> vcpkg and make sure AutoLink is enabled.
It has been fixed by the developers, on GitHub : https://github.com/microsoft/vcpkg/issues/14127
I literally just got Python.h to link to my Visual Studio 2017 IDE and then when I ran it, it spat this error out for me.
I use VS2017, and I am learning C++, so I have no idea why this is happening. I linked my Python.h file's directory in the project properties.

Try to include pythonxx.lib(such as python26.lib) in your references.
The answer is simple, like #Xiaoying Sun has stated, put the python38.lib file in your references, however, you're required to put it in your VC++ directories, this way it will work.
I feel like this question should have been asked already but I haven't been able to find any solutions to accomplish this. But basically I'm going through the youtube lecture videos for Stanford's CS106B course on C++ and I'd like to use their libraries in my Visual Studio 2010, but i'm a VS newbie so I'm not sure how to get the include to work. I've tried to include the path to Project|Options|Include Directories but I get the following error

Update: I downloaded the library from here: http://stanford.edu/~stepp/cppdoc/
And i'm using the Visual Studio IDE.
Any assistance would be awesome, and then I'd know how to include external libraries!

I tried all possible options but could not got the solution. Please help me out
I had the same problem and it was just that I wasn't linking the library.
You need to include the library in the Visual Studio project.
How to add additional libraries to Visual Studio project?
