Hi! I am the author of Synfig CMake scripts and i'm glad someone actually uses them.
1) That's probably right, but i was basically adding directories as i needed them and synfig-core only needs src/ to be built. 2) The build instruction is imperfect (i just noticed it misses some build/ directory creation steps), but it does have build_images step mentioned: `cmake --build . -- build_images`. It does take some time to finish and doesn't build all icons, but at least most of them, (basically, enough to be usable by me). 3) The algorithm there is pretty much "take all .sif and render them to .png". 4) There's not much reason to make CMake scripts compatible with pkg-config as the only user of that is Synfig's autotools scripts and that, hopefully, will fall out of use as CMake build matures. Besides, i'm not entirely sure they will be abi-compatible due to possible different flag usage. 6) Yeah, should add that to CMake somewhere. The source of these issues is that the things work for me and nobody else seems to be interested in improving. I might fix them sooner or later, but generally help is much appreciated here as i have my hands full with actual development and am not all that fluent with CMake. My reason for creating these build scripts in the first place was only enabling me to write tests without learning autotools and speeding up build (due to much faster configure phase and ninja being somewhat faster than make).
