C++/CLI DLL project stops linking after conversion from VS2008 to VS2010 - c++

I converted a perfectly working Managed C++ DLL project that uses Unmanaged C++ LIBs from VS2008 to VS2010. Beforehand I separately rebuilt the LIBs with VS2010 (they are part of another project that I have no authority over). However, after conversion my managed DLL project stopped linking giving me few dosen of LNK2001 error messages (see the sample below). All errors about "std" entities defined within "string" and "iosfwd" headers. Which compiler/linker settings am I missing?
Thanks in advance for your help.

Finally found it (thanks Hans Passant for the tip!) I had a few files that were still built by VS2008 and that caused the issue. Thanks to everyone who bothered to add a comment.

Fixing unresolved external symbols using Boost.Python

I am trying to build a library and getting several "unresolved external symbol" errors. I am trying to fix one of those errors which should give me an idea of how to proceed. That error is: unresolved external symbol IsProcessorFeaturePresent. As per my understanding since this is not part of the code I am trying to build this must be present in a "lib" file. According to this that lib file should be kernel32.lib. Now there are several kernel32.lib files present under "Windows Kits". Which I suppose should be included by default when compiling in Visual Studio Developer Command Prompt as it should be a part of the environment. I still added a path "C:\Program\ Files\ (x86)\Windows\ Kits\8.1\Lib\winv6.3\um\x64" to <library-path> under #requirements in JamFile of the library I have also added "<include>C:\Program\ Files\ (x86)\Windows\ Kits\8.1\Include\um" to it. But there is no change in the error. How do I find out which file does it require to be included?
Note: This question is different from how to resolve unresolved external symbol error, I have already gone through answers to that question and now I am trying to apply it to this particular error.
Edit:I am trying to build the libtorrent library which depends on Boost.Python. I built Boost.Python using --with-python=C:\Python27 in Boost's root directory. After This I have added BOOST_ROOT to the environment variables and also added it to path. After that I am trying to build libtorrent python bindings using bjam variant=release memory-model=64 The complete error logs are here.
Edit 2: Following up on the comments to this question I have added the required libraries to JamFile and the number of errors has been reduced from 187 to 11. The remaining errors are:

On inspection of libboost_python-vc141-mt-1_65_1.lib at C:\boost_1_65_1\stage\lib (using dumpbin /EXPORTS) I checked that all the symbols are present in the output of dumpbin, for example searching for identity_function I get this line:

I am including this lib file in my JamFile. What else am I missing? Is there some option I need to pass while building Boost.Python currently I am building it using bjam --with-python variant=release address-model=64

Following RbMm's suggestion I included the libaries in the JamFile and it removed a lot of unresolved external symbol errors. The rest of the errors were fixed by building Boost.Python as shared and including the lib file. Now I have a completely different unrelated error.

Notes:
compiled all projects with MD or MD(d)
at the moment no tests defined (only main)
Anything still wrong here? Thanks for any help!

Ok, I found the solution for VS2012:
use the gtest-md solution file if your other projects are compiled with /md
set _VARIADIC_MAX=10 as preprocessor definition
maybe you have to change the compiler to VS2008 if your project-to-test also use this compiler

Linker errors while using VS-C++ 2010 Express edition

Im a C++ and VS noob. Im trying to learn the CS 106b course(Link to course page) by Stanford for programming using C++. However, Im running into a few issues as I try to setup the startup code.
For instance, the following code,
#include <iostream>
#include "graphics.h"
using namespace std;
int main(){
initGraphics();
setColor("BLUE");
fillRect(50,50,300,150);
setFont("Times New Roman");
setColor("WHITE");
drawString("Hello World Graphically!!",60,140);
return 0;
}
compiles successfully, but throws the following linker errors.

I m only including tag.lib from taglib/taglib/Release folder . Is there some other library I m missing out?

MySQL libraries are not linked

I use cmake for building my project files.
this are my additional link libraries:

gdi32.lib
winspool.lib
shell32.lib
