### Install VarFlow Python Package

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/README.md

After building, install the VarFlow Python package in development mode using setup.py.

```bash
python setup.py develop
```

--------------------------------

### Build VarFlow with OpenCV on Linux

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/README.md

If OpenCV is not found, specify its directory using the -DOpenCV_DIR flag during CMake configuration. This example assumes OpenCV is installed at /usr/local/software/opencv.

```bash
mkdir build
cd build
cmake -DOpenCV_DIR=/usr/local/software/opencv/share/OpenCV ..
make
```

--------------------------------

### Find and Include OpenCV

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/CMakeLists.txt

Locates the OpenCV library and includes its header directories. Ensure OpenCV is installed and discoverable by CMake.

```cmake
find_package( OpenCV REQUIRED )
include_directories(SYSTEM ${OpenCV_INCLUDE_DIRS})
```

--------------------------------

### Build FlowExample Executable

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/CMakeLists.txt

Compiles an executable named 'FlowExample' using the provided source files. This is typically the main application entry point.

```cmake
add_executable( FlowExample example.cpp VarFlow.cpp)
```

--------------------------------

### Build VarFlow on Windows

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/README.md

Use these CMake commands to build VarFlow on Windows with Visual Studio 2015.

```bash
mkdir build
cmake -G "Visual Studio 14 2015 Win64" ^
-DCMAKE_BUILD_TYPE=Release ^
-DCMAKE_CONFIGURATION_TYPES="Release" ^
..
```

--------------------------------

### Configure CMake for Visual Studio 2015 (Release)

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/windows_cmake_command.txt

Use this command in the root directory of your project to generate Visual Studio solution files. Specify the generator for your Visual Studio version and the desired build type.

```bash
cmake -G "Visual Studio 14 2015 Win64" ^
-DCMAKE_BUILD_TYPE=Release ^
-DCMAKE_CONFIGURATION_TYPES="Release" ^
..
```

--------------------------------

### Build VarFlow on Linux

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/README.md

Use these CMake commands to build VarFlow on Linux. Ensure you are in the build directory.

```bash
mkdir build
cd build
cmake ..
```

--------------------------------

### Link Libraries to Targets

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/CMakeLists.txt

Links the necessary libraries to the 'FlowExample' executable and the 'varflow' shared library. This ensures all dependencies are resolved during the build process.

```cmake
target_link_libraries( FlowExample ${OpenCV_LIBS} )
target_link_libraries( varflow ${OpenCV_LIBS} )
```

--------------------------------

### Set Minimum CMake Version and Project Name

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/CMakeLists.txt

Specifies the minimum required CMake version and sets the project name. This is standard practice for CMake projects.

```cmake
cmake_minimum_required(VERSION 2.8)
project( Varflow )
```

--------------------------------

### Build VarFlow Shared Library

Source: https://github.com/hzzone/precipitation-nowcasting/blob/master/experiments/VarFlow/CMakeLists.txt

Creates a shared library named 'varflow' from the specified C++ source files. This library can be dynamically linked by other executables.

```cmake
add_library(varflow SHARED c_api.cpp VarFlow.cpp)
```
