How do I build libcurl for 64-bit Windows in/using Visual Studio 2010?
So initially, I followed the instructions of BUILD.WINDOWS.txt and I was able to get libcurl building 32-bit by creating a new file winbuild.bat and placing it in the root directory of my curl folder:
CALL "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat"
CD winbuild
DEL CURL_OBJS.inc
DEL LIBCURL_OBJS.inc
DEL vc100.idb
nmake /f Makefile.vc mode=dll VC=10 ENABLE_WINSSL=yes GEN_PDB=yes MACHINE=X86
CD ..
EXIT /B 0
I then went to File / New / Project from Existing Code... / Visual C++ / Use external build system / Build command line: winbuild.bat. I tried to create a new Platform in my properties for x64, with winbuild64.bat:
CALL "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\x86_amd64\vcvarsx86_amd64.bat"
CD winbuild
DEL CURL_OBJS.inc
DEL LIBCURL_OBJS.inc
DEL vc100.idb
nmake.exe /f Makefile.vc mode=dll VC=10 ENABLE_WINSSL=yes GEN_PDB=yes MACHINE=x64 DEBUG=no
CD ..
EXIT /B 0
But this is my output for winbuild64.bat:

I was able to build 32-bit in Command Prompt, and I tried both Visual Studio Command Prompt (2010) and Visual Studio x64 Win64 Command Prompt (2010), but neither worked.
I've read this answer and it seems like I can create a project and then run nmake from inside Visual Studio 2010, but I can't figure out how to have it work within the winbuild directory during compilation.
The code in my project is finished and all I have left to do is build the dependencies to get the dll and lib files for deployment. I've been debugging off of a libcurl 7.25.0 build this whole time lol and I'm trying to build 7.47.1. All help appreciated.
Answer
Its simple.
1: install windows SDK, VS with VC,
2: download latest curl release
3: Win+R cmd
4: cd to to [your vs installation]\VC\bin[amd64 or x86_amd64], use the folder according to the type of build you want (i used amd64 on a 64bit machine to use curl dll on my 64 win 8.1
5: run vcvars64 or vcvars32 accordingly
6: cd to [extracted CURL dir]\winbuild
7: run:
nmake /f makefile.vc ENABLE_WINSSL=yes mode=dll MACHINE=x64 VC=13
use x64 and VC version according to your installation. e.g. VS 2013 is 13
It will take some time and build a dll in \CURL\builds\libcurl-vc13-x64-release-dll-ipv6-sspi-winssl or \CURL\builds\libcurl-vc13-x86-release-dll-ipv6-sspi-winssl
if cmd can't find nmake, in the system PATH variable, add this:
blah blah;bleb, bleh bleh;[your VS installation dir]\VC\bin
confirm that the specified folder contains an nmake.exe.
