Recently I installed CodeBlocks and Borland C++ as the compiler to just make a C program. But when I started to build it gives an error.

Those missing symbols are from the Borland-C++ Compiler libraries.
Since you're using Code::Blocks add these to the Link Libraries pane on your project's build options (Menu Bar->Project Options->Linker Settings):
cw32.lib - Single Threaded
cw32i.lib - Single Threaded (Dynamic)
cw32mt.lib - Multi Threaded
cw32mti.lib - Multi Threaded (Dynamic)

I am trying to build Vivek's Virtual Camera on Windows 10.
For that I need to have Win7Samples/multimedia/directshow/baseclasses
I have downloaded baseclasses and built it using Visual Studio 2019.
Now I am ready to build Virtual camera filter. I followed few requisite steps
git clone https://github.com/roman380/tmhare.mvps.org-vcam
cd tmhare.mvps.org-vcam\Filters
Then I tried to open Filters.dsp in Visual Studio 2019 which asked me to do one-way upgrade
Added C:\Users\alokm\tmp\Windows-classic-samples\Samples\Win7Samples\multimedia\directshow\baseclasses in Additional Include Directories
Added C:\Users\alokm\tmp\Windows-classic-samples\Samples\Win7Samples\multimedia\directshow\baseclasses\Debug to Addition Library Directories
After all these steps I tried to build by hitting Build >> Build Solution
But I am getting lot of linker errors.

Where I am wrong? How to make this working?
The problem building the project is coming from this:
The project source code has a dependency of DirectShow BaseClasses which is no longer a part of Windows SDK
The project has too many settings diverged from defaults; with current Visual Studio it becomes a problem
I updated the github repository and changed the project settings to make the project build (Visual Studio 2019 Communitty) and run: most of the C++ project settings are reverted and DirectShow BaseClasses are used in the build configuration from github.
Check out README.md there, follow build steps (which require to pull Windows SDK Samples first, and build DirectShow stuff there), have DLLs registered (regsvr32) and finally you will have the filter generating video with random data:

1>..\..\..\..\build\Win32\VC14\LIB Release - DLL OpenSSL\curl.exe : fatal error LNK1120: 35 unresolved externals
According to OpenSSL & nghttp2 path on my computer, I have added the following to curl & libcurl project:
I have added the following folders to my additionnal library directories (curl project->properties->configuration properties->linker->general->additionnal library directories) :
C:\OpenSSL-Win32\lib
C:\nghttp2-1.22.0\lib
And added for both curl and libcurl project additionnal include directories (both projects->properties->configuration properties->c/c++->general->additionnal include directories) :
C:\OpenSSL-Win32\include
C:\nghttp2-1.22.0\lib\includes
I also added the definition of USE_NGHTTP2 to both project preprocessor definitions (both projects->properties->configuration properties->C/C++->Preprocessor->Preprocessor Definitions) in order to compile with nghttp2.
Finally, I am building using configuration "LIB Release - DLL OpenSSL" with target platform Win32.
Edit: the issue seems to be related to nghttp2 as I successfully build without the NGHTTP2 preprocessor definition.
I am surely missing something but I can't see what at the moment.
Thank you for your assistance

I am having problem figure out how to use libusb, I put "libusb-1.0.18-rc1\libusb"
in include directories (using Visua Studio), but it doesn't work.
Can anyone enlighten me. Thanks a lot!

If you havne't done so already you will need to build the libraries you will be linking to, they are located in \libusb-1.0.18-rc1\msvc. There are multiple projects there depending on your Visual Studio version and whether you want a DLL or a static LIB file.
In either case you will need to right click on your project, then under Configuration Properties -> Linker -> Input -> Additional Dependencies add a reference to the LIB file you created. If you are linking to the static LIB file you're done, it will build the code in to your executable. If you're linking to the LIB file for the DLL make sure the DLL is available in your execution path. In either case this should resolve your unresolved externals.
I think you must take the 32-Bit Version of the libusb-Library/DLL and ensure 32 Bit Compile at Project Properies. That solved my Problem with LNK2019.
