This guide will help you build and install QtAliceVision plugin.
QtAliceVision requires:
- Qt5 (== 5.15.2, make sure to use the same version as the target application)
- AliceVision
- OpenImageIO (>= 2.1) - with OpenEXR support for depthmaps visualization
- Alembic (>= 1.7)
- CMake (>= 3.11)
- On Windows platform: Microsoft Visual Studio (>= 2019)
Note for Windows: We recommend using VCPKG to get Alembic. Qt can either be installed with VCPKG or the official installer.
In the following steps, replace <INSTALL_PATH> with the installation path of your choice.
We will use "NMake Makefiles" generators here to have one-line build/installation, but Visual Studio solutions can be generated if need be.
From a developer command-line, using Qt 5.15.2 (built with VS2019) and VCPKG for OIIO:
set QT_DIR=/path/to/qt/5.15.2/msvc2019_64
set AV_DIR=/path/to/aliceVision/cmake/folder
cmake .. -DCMAKE_TOOLCHAIN_FILE=%VCPKG_ROOT%\scripts\buildsystems\vcpkg.cmake -DAliceVision_DIR=%AV_DIR% -DCMAKE_PREFIX_PATH=%QT_DIR% -DVCPKG_TARGET_TRIPLET=x64-windows -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=<INSTALL_PATH>
nmake install
export QT_DIR=/path/to/qt/5.15.2/gcc_64
export OPENIMAGEIO_DIR=/path/to/oiio/install
export ALEMBIC_DIR=/path/to/alembic/config
cmake .. -DAliceVision_DIR=$AV_DIR -DOPENIMAGEIO_LIBRARY_DIR_HINTS:PATH=$OPENIMAGEIO_DIR/lib/ -DOPENIMAGEIO_INCLUDE_DIR:PATH=$OPENIMAGEIO_DIR/include/ -DAlembic_DIR=$ALEMBIC_DIR -DCMAKE_PREFIX_PATH=$QT_DIR -DCMAKE_INSTALL_PREFIX=<INSTALL_PATH> -DCMAKE_BUILD_TYPE=Release
make install
Once built, setup those environment variables before launching your application:
# Windows:
set QML2_IMPORT_PATH=<INSTALL_PATH>/qml;%QML2_IMPORT_PATH%
set QT_PLUGIN_PATH=<INSTALL_PATH>;%QT_PLUGIN_PATH%
# Linux:
export QML2_IMPORT_PATH=<INSTALL_PATH>/qml:$QML2_IMPORT_PATH
export QT_PLUGIN_PATH=<INSTALL_PATH>:$QT_PLUGIN_PATH
