Windows build fails if path has whitespace

[Isaac Brodsky]

What happens?

If the path the extension is built from has a space in it, configuring the build fails.

Building from a path that does not contain whitespace does work.

To Reproduce

git clone https://github.com/duckdblabs/sqlite_scanner.git sqlite\ scanner
cd sqlite\ scanner/
git submodule update --init --recursive
make release

$ make release
mkdir -p build/release && \
cmake   -DDUCKDB_EXTENSION_NAMES="sqlite_scanner" -DDUCKDB_EXTENSION_SQLITE_SCANNER_PATH="E:/Dev/ scanner/" -DDUCKDB_EXTENSION_SQLITE_SCANNER_SHOULD_LINK=0 -DDUCKDB_EXTENSION_SQLITE_SCANNER_LOAD_TESTS=1 -DDUCKDB_EXTENSION_SQLITE_SCANNER_TEST_PATH=E:/Dev/ scanner/test -DDUCKDB_EXTENSION_SQLITE_SCANNER_INCLUDE_PATH="E:/Dev/ scanner/src/include"   -DEXTENSION_STATIC_BUILD=1 -DCMAKE_BUILD_TYPE=Release -DEXTENSION_STATIC_BUILD=1 -DBUILD_EXTENSIONS="tpch" -DOSX_BUILD_ARCH= -S ./duckdb/ -B build/release && \
cmake --build build/release --config Release
