# Download extensions:

EXTENSION_NAME=MeshToLabelMap
git clone https://github.com/NIRALUser/MeshToLabelMap ${EXTENSION_NAME}
Slicer_EXTENSION_SOURCE_DIRS="/work/${EXTENSION_NAME}"

EXTENSION_NAME=BoneTextureExtension
git clone git://github.com/Kitware/${EXTENSION_NAME} ${EXTENSION_NAME}
Slicer_EXTENSION_SOURCE_DIRS="${Slicer_EXTENSION_SOURCE_DIRS};/work/${EXTENSION_NAME}"
echo "Slicer_EXTENSION_SOURCE_DIRS: ${Slicer_EXTENSION_SOURCE_DIRS}"

# Download corresponding build environment and generate convenience script
docker run --rm slicer/${DOCKER_IMAGE} > ~/bin/slicer-${DOCKER_IMAGE}
chmod u+x ~/bin/slicer-${DOCKER_IMAGE}

# Configure Slicer
slicer-${DOCKER_IMAGE} cmake \
  -BSlicer-build -HSlicer \
  -GNinja \
  -DCMAKE_BUILD_TYPE:STRING=Release \
  -DSlicer_USE_SimpleITK:BOOL=OFF \
  -DBUILD_TESTING:BOOL=OFF \
  -DSlicer_EXTENSION_SOURCE_DIRS:STRING=${Slicer_EXTENSION_SOURCE_DIRS} \
  -DSlicer_VTK_VERSION_MAJOR:STRING=9 \
  -DSlicer_REQUIRED_QT_VERSION:STRING=5

# Qt5_DIR will be populated, because it is already in the system path.

# Build Slicer
slicer-${DOCKER_IMAGE} cmake --build Slicer-build

# Package Slicer
slicer-${DOCKER_IMAGE} cmake --build Slicer-build/Slicer-build --target package

You can then unpack the generated ${ROOT_DIR}/Slicer-build/Slicer-build/Slicer-XXX-YYY.tar.gz anywhere to run Slicer.
