Looking for help to build under Windows

Source/filter types
Face Tracker (source code)

Describe your problem
I would like to do some modifications to the plug-in (source code) and then compile it. I am on Windows. I have a working development environment for obs-studio, which successfully compiles and runs obs-studio itself.

Now I am looking for a way to do the same for obs-face-tracker.

Desktop (please complete the following information):

• OS: Win10
• OBS Version: e284a79b48f5524a37a6e515667c8bedb0bce3f0
• Face Tracker Version: 573da1a

Additional context
I see the steps in the file .github/workflows/main.yml, but I don't know GitHub Workflows, and I am new to CMake as well, so I do not know, how to perform those steps on my local computer to generate a working build environment, including an .sln file for the development environment Visual Studio.

Thank you kindly in advance.

At first, you need to have directory structure like below.

• obs-studio
• obs-face-tracker
  • dlib (If not found, please go to obs-face-tracker directory and run git submodule update --init, this directory will be created.)

And, also download model files from https://github.com/davisking/dlib-models; mmod_human_face_detector.dat.bz2 and shape_predictor_5_face_landmarks.dat.bz2.
Extract them. Place mmod_human_face_detector.dat and shape_predictor_5_face_landmarks.dat under obs-face-tracker/data/dlib_cnn_model and obs-face-tracker/data/dlib_face_landmark_model, respectively.

Then, go to the directory obs-face-tracker and follow the command below.

obs-face-tracker/.github/workflows/main.yml

Lines 376 to 385 in 573da1a

	$CmakeArgs = @(
	'-G', "${{ env.visualStudio }}"
	'-DQT_VERSION=${{ steps.obsdeps.outputs.OBS_QT_VERSION_MAJOR }}'
	'-DCMAKE_SYSTEM_VERSION=10.0.18363.657'
	"-DCMAKE_INSTALL_PREFIX=$(Resolve-Path -Path "./obs-build-dependencies/plugin-deps-${{ matrix.arch }}")"
	"-DCMAKE_PREFIX_PATH=$(Resolve-Path -Path "./obs-build-dependencies/plugin-deps-${{ matrix.arch }}")"
	)
	cmake -S . -B build @CmakeArgs
	cmake --build build --config RelWithDebInfo -j 4
	cmake --install build --config RelWithDebInfo --prefix "$(Resolve-Path -Path .)/release"

@CmakeArgs is a variable and you may extract the line 383 like make -S . -B build -G "Visual Studio 17 2022" -DQT_VERSION=6 -DCMAKE_SYSTEM_VERSION=10.0.18363.657
And also need to add the options starting with -DCMAKE_INSTALL_PREFIX= and -DCMAKE_PREFIX_PATH= so that make can find libobs configuration file but I don't know exactly how it should be configured.

Usually I don't use Windows. Above comment might not be insufficient.

Thank you, this just gave me the right amount of push.

I started with your cmake suggestion, and then kept adding directories for libraries cmake reported as not found, until finally this gave me no errors anymore:

cmake -S . -B build -G "Visual Studio 17 2022" -DQT_VERSION=6 -DLIBOBS_INCLUDE_DIR=$PWD/../obs-studio/libobs -DLIBOBS_LIB=$PWD/../obs-studio/libobs -Dlibobs_DIR=$PWD/../obs-studio/build_x64/libobs -Dw32-pthreads_DIR=$PWD/../obs-studio/build_x64/deps/w32-pthreads/ -Dobs-frontend-api_DIR=$PWD/../obs-studio/build_x64/UI/obs-frontend-api/ -DQt6_DIR=$PWD/../obs-studio/.deps/obs-deps-qt6-2023-11-03-x64/lib/cmake/Qt6/ -DQt6CoreTools_DIR=$PWD/../obs-studio/.deps/obs-deps-qt6-2023-11-03-x64/lib/cmake/Qt6CoreTools/ -DQt6GuiTools_DIR=$PWD/../obs-studio/.deps/obs-deps-qt6-2023-11-03-x64/lib/cmake/Qt6GuiTools/

I assume there is a better way, but I put it here for future reference for others who are similarly clueless about cmake as I am but might want to work on this.

and I needed do update libvisca after this to be able to do a Debug build:

cd libvisca
git pull origin HEAD
