0006 This CMake file builds a patched libraqm as a static library to be linked from
0007 Krita (libkritaflake). We use FetchContent to download a copy of the unmodified
0008 libraqm source and patch it locally.
0009
0010 FetchContent provides a way to use existing source instead of a downloaded copy.
0011 By setting `FETCHCONTENT_SOURCE_DIR_LIBRAQM_SRC` to the path of a local copy of
0012 the patched libraqm source, you can skip the download step, and you will be
0013 able to modify the local copy of the libraqm source to test out changes.
