Oh, right, that was the missing bit. Problem solved.
Thank you very much for your help

Is nghttp2.lib is listed in the to the linker input settings
(Properties->Configuration Properties->Linker->Input->Additional
Dependencies)?
The "additional library directories" only tells visual studio where to
find the input libs, you also have to tell it which libraries actually
need to be linked in.

Hello everyone,
I am currently trying to build Libcurl 7.54.0 with OpenSSL and
HTTP2 on windows 10 using Visual Studio 2015 and I am getting
these errors in the build log at the end of generation:

----------------------------------------------------------------------------------------
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.
I am surely missing something but I can't see what at the moment.
Thank you for your assistance
Lucas
