I am following the basic tutorial on https://www.music.mcgill.ca/~gary/rtmidi/ and I cannot seem to make it past the first step in "Getting Started."
Originally I was only getting two errors, one of which was a "LNK2019 - unresolved external symbol" error, which I fixed by linking rtmidi.lib and rtmidid.lib
Now I have a huge block of errors that I can't make any sense of
rtmidi.lib(RtMidi.obj) : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance

Obviously on lines 7-25 it's looking for a library or something that doesn't exist, but gives no hints as to what it is. The rest however, I can't even begin to figure out. Any Ideas?
I read somewhere else to change the project option to "Release" Which does get rid of the above messages, but instead replaces them with
RTMIDI_test.obj : error LNK2001: unresolved external symbol "public: __thiscall RtMidiIn::RtMidiIn(enum RtMidi::Api,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,unsigned int)" (??0RtMidiIn##QAE#W4Api#RtMidi##V?$basic_string#DU?$char_traits#D#std##V?$allocator#D#2##std##I#Z)
C:\Users\Zach\Desktop\RTMIDI_test\Release\RTMIDI_test.exe : fatal error LNK1120: 1 unresolved externals
Most of the link errors tell you what you need to do to fix them (at least in combination with a bit of googling)
rtmidi.lib(RtMidi.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in RTMIDI_test.obj
rtmidi.lib(RtMidi.obj) : error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MD_DynamicRelease' doesn't match value 'MDd_DynamicDebug' in RTMIDI_test.obj
So RTMIDI_test.cpp has been compiled with a different value for _ITERATOR_DEBUG_LEVEL than in rtmidi.lib. The next line says that you are trying to link your debug project with a release build of rtmidi.lib. You should change this to link against the debug version instead which should remove some or all of the other warnings and errors.
rtmidi.lib(RtMidi.obj) : error LNK2001: unresolved external symbol __imp__midiInUnprepareHeader#12
midiInUnprepareHeader and the other midiIn* functions live in winmm.lib (see the docs), so you also need to link against that.

I'm total begginer in Cmake and I don't know where I have to put code. My problem is:
CMake Deprecation Warning at CMakeLists.txt:81 (cmake_policy):
The OLD behavior for policy CMP0020 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

What's happening is that the default libraries specified by one or more objects (probably in a library you're using) is asking to be linked with an runtime library that isn't the same as what your project is using.
The docs on LNK4098 are reasonably clear about what's going on and how to troubleshoot the problem.
Don't add the libraries to ignore in the 'additional options', add them under Linker/Input/ Ignore specific default libraries' (I see you already have glfw3.lib there, just add libcmt.lib separated by a semicolon).

I wrote a code in C++ called FaceTracker.cpp and other code in Matlab that do some analyzes and statics.
What I need to do is adding a button in matlab that calls the FaceTracker when being pressed. I tried to use the following command:
system (['FaceTracker.exe <' nameOfVideo]);
but it doesn't work. It opens the FaceTracker.exe GUI, then it stops ! (Like when internet explorer or any other program does sometimes\hang) with the msg "FaceTracker.exe stoped working.
When I tried to run the .exe from command prompt it showed me the following error:
Assertion Faile: Type == IO::TRACKER ... Debug error! R6010 - abort() has been called.
From what i understd from the answers\ other sites is that I need to statically link libraries.
I read in one site that I need to make the following changes:
The CRT:
• Configuration Properties -> C/C++ -> Code Generation: Where it reads Runtime Library, change to Multi-Threaded (/MT).
The manifest must go:
• Configuration Properties -> Manifest Tool -> Input and Output: Where it reads Embed Manifest, change to No.
But when I do it (Change to /MT) I start getting the following errors:

Any Suggestions?
What do I Have to do in order to be able to use the FaceTracker.exe in every computer, also the ones that doesn't have c++\vs compiler?
besides, why does my program OPENS when I call it from matlab but then Hangs\stops working?
Thank in advance.
This almost certainly has nothing to do with debug versus release or whether mt is enabled. You are not making a matlab extension, just using a binary from the command line. If the program works when you type things in from the command line, it should work when called from Matlab unless you are running low on memory (highly unlikely also).
I would examine the contents of . .
['FaceTracker.exe < ' InputVid]
...and copy and paste the string directly into the command line (system, not Matlab) to see if you can replicate the error. The error is most likely occurring because your exe is not handling the file string well.
Try putting the inputvid, calling m file, and FaceTracker.exe in the working directory to make the most simple scenario. If that works, make things more complex by placing input vid into another directory and bug hunt from there.
Best of luck!
I think this exe file depends on some other libraries. You should copy them into one of the directories in your system parameter PATH. Or you can use the static link option when build your project.
Your applications don't require the entire Visual C++ compiler to be installed, just the runtime library. Microsoft has a free redistributable which can add this runtime library to any computer. You can find vcredist_x86.exe in your Visual C++ install path, or download it from http://www.microsoft.com/en-us/download/details.aspx?id=8328

Check Linker->Input->Additional Dependencies settings in the Release configuration ; you have undoubtedly forgotten to include the OpenCV libraries. Just copy-paste them from the Debug configuration, but don't forget to remove the d suffix.
E.g. cv210.lib : Release mode and cv210d.lib : Debug mode.
You are not including the same libraries in your release build that you include in your debug build. "unresolved external symbol" means it cannot find the implementation for a function you are referencing.
This happens when you give Additional Dependencies to Debug mode but not in Release.
