cmake: modules: extension: Fix dts file watch (d32ad623) · Commits · Wenxi XU / zephyr

Fixes an issue in the code that processes the output file of a compiler to see which files should be watched, the compiler can combine multiple files into a single line instead of putting them each on separate lines if the length of the file paths is short, therefore account for this and split it up into multiple elements Signed-off-by:
