To amplify: if your distributions doesn't have Vc 1.0 or 1.2 yet, you can do the \
following:

mkdir ~/dev/b
mkdir ~/dev/d
mkdir ~/dev/deps
cd b
cmake ../krita/3rdparty/ -DINSTALL_ROOT=~/dev/deps -DEXTERNALS_DOWNLOAD_DIR=~/dev/d \
-DCMAKE_INSTALL_PREFIX=~/dev/deps cmake --build . --config Release --target ext_vc

and then configure krita like normal, with an extra -DCMAKE_PREFIX_PATH pointing to \
~/dev/deps

Or you can configure the 3rdparty deps project to directly install to your ~/dev/i \
folder.

If you build and install krita somewhere else than ~/dev/i, adapt.
