|
|
|

|
|
|
|
* In some cases, it takes a long time to select a device (RTL-SDR in perticular)

## The build
|

|
|
|
```
|
|
|
|
|
mkdir build
|
|
|
|
|
cd build
|
|
|
|
|
cmake .. "-DCMAKE_TOOLCHAIN_FILE=C:/Users/Alex/vcpkg/scripts/buildsystems/vcpkg.cmake" -G "Visual Studio 15 2017 Win64"
|
|
|
|
|
cmake --build . --config Release
|
|
|

|
|
|
## Copying over needed directories
|
|
|
|
|
The last step of the build process is copying the `bandplans` and `res` directories to the output directory.
|
|
|
|
|
If you followed the steps above, it should be `build/Release`.
