*Note: The correct sqlite3.dll is automatically copied to the output folder when building for x86-windows. You will need to distribute this along with your application.*
Unlike other platforms, we do not automatically add the `include\` directory to your compilation line by default. If you're using a library that does not provide CMake integration, you will need to explicitly search for the files and add them yourself using [`find_path()`][1] and [`find_library()`][2].
```cmake
# To find and use catch
find_path(CATCH_INCLUDE_DIR catch.hpp)
include_directories(${CATCH_INCLUDE_DIR})
# To find and use azure-storage-cpp
find_path(WASTORAGE_INCLUDE_DIR was/blob.h)
find_library(WASTORAGE_LIBRARY wastorage)
include_directories(${WASTORAGE_INCLUDE_DIR})
link_libraries(${WASTORAGE_LIBRARY})
# Note that we recommend using the target-specific directives for a cleaner cmake:
# target_include_directories(main ${LIBRARY})
# target_link_libraries(main PRIVATE ${LIBRARY})
