[Walkthrough] Build OBS-Studio for win64

Hey Folks...
ED: When i visit bigger Projects, im always unsure about build problems and read for easy reproduceable success stories. So heres one: I just followed the steps given within the OBS-Studio Wiki and succeeded with it. - Here are some shortcuts if your like me and just want to build OBS-Studio for win64.-

Ed: On MSV2017 ? Just follow the guide and remember to use "Quties" 2017 deps..

1) Install MSVC 2015 http://go.microsoft.com/fwlink/?LinkId=691126
Infos: https://msdn.microsoft.com/en-us/library/ms235639.aspx
-> Make sure to do a [custom install]
-> and choose to include the Windows 8 SDK and ATL/MFC :

2) Install CMake https://cmake.org/download/#latest (win64 msi)

3) Install GIT https://git-scm.com/download/win


4) Install QT https://www.qt.io/download

Note: You only need the QT libs when you want to build the gui too.
Note: Only the MSVC2015 Libs are relevant here, so install them like:

5) Fetching the soures
-> Create a Directory -eg "OBS-Studio-git"
-> Open a git-bash via rightClicking in the above Folder, and invoke:
git clone --recursive https://github.com/jp9000/obs-studio.git
-> Create a Directory with the name "build" within the downloaded obs sources.

6) Build Dir
Within CmakeGui [Where are the sources] choose the root folder of the git-fetched OBS-Studio Sources.
In the second Box [Where to build the binaries] choose the "build" Directory created in the Step before.

7) OBS-Studio Dependencies https://obsproject.com/downloads/dependencies2015.zip
-> copy the contents, at least the Dir [win64] to the [deps] Dir within the OBS Sources.
-> Create a CMake Var within CMake-Gui using [+AddEntry] Name: "DepsPath" Type [Path]
-> Give it the full include path [....deps\win64\include]

8) (plugin-only-dev)
-> If you want to build with DISABLE_UI you dont need to extra download QT.
-> But then you need to create another CMake Var :
-> using [+AddEntry] Name: DISABLE_UI Type: [Boolean] and set that to true.

9) Configure Button
Within CMake Gui, hit Configure and select "VisualStudio 14 2105 64bit"

....Drink Coffee...

Okay -Everything should do fine now (besides an unproblematic Deprecation warn)
CMake Deprecation Warning :SWIG_ADD_MODULE is deprecated. Use SWIG_ADD_LIBRARY instead.


10) Generate Button
...Just Hit [Generate] to create the build files....

11) Finally - The actual Build
-> open a shell within the "build" dir
-> Do a cmake --build . --config Release (or --config Debug)

Have a nice Day!

Add: If you are searching for a minified Version of QT 5.10 for MSVC2015 (136Mb instead of multiple Gigabyte, Debugging Symbols included) for fulfilling OBS Gui Deps - have a look here (Google Drive Link)

Hi, I'm glad you got it compiling, although I'm confused. Please forgive me for misunderstanding, but if the wiki exists and you just followed the wiki, what made you make this forum post exactly? I don't see anything that deviates from the norm in particular. I mean the instructions are technically already in there. I'm not saying you shouldn't have necessarily made any forum posts, I'm just sort of trying to understand what the intent was due to the redundancy of this particular forum post.

Hi, I had problem when I compile it in DISABLE_UI mode. There are lots of error related to errro LNK2019, or errors from Windows Kit.
WHAT's WRONG?
Can you help me?

Who would refuse well organized instructions with images? It's much easier to read than the offical wiki. I prefer this post.
 
Where does one find the QT MSVC package(s)? Downloading QT requires payment, or downloading source to build. The docs say this:

"Qt5 (Grab the MSVC package for your version of Visual Studio)
We currently deploy with Qt 5.15.2"

... but where does one "Grab" these? I've heard about a ZIP file that can be downloaded that has all the required QT files? Anyone know what that link is?
