My build directories are:
~/build/perfecttin/cdbg for the debug build (prefix $HOME),
~/build/perfecttin/crel for the release build (prefix $HOME),
~/build/perfecttin/cins for the release build (prefix /usr/local),
~/build/perfecttin/cafl for fuzzing (prefix $HOME, but installing disabled),
and the same with 'g' instead of 'c', compiled with g++ instead of clang. I 
added a desktop file and installed it and the icon under $HOME, then symlinked 
~/share/applications/perfecttin.desktop to ~/.local/share/applications/
perfecttin.desktop . It showed up in the menu, but had no icon and didn't run. 
I then installed under /usr/local and it worked perfectly.

Apparently I should install under ~/.local/, but the only directory under 
~/.local is share; ~/.local/bin, ~/.local/include, and ~/.local/lib do not 
exist. Should I add ~/.local/bin to PATH, or should I make symlinks in ~/bin/?
