I've been trying to compile Sigil for hours on Ubuntu 16.04 (Xenial) 64-bit, but I've been getting all kinds of errors.
Configuring Sigil for building appears to go well:
Code:
$ cmake -G "Unix Makefiles" -DCMAKE_PREFIX_PATH=/opt/Qt5.5.1/5.5/gcc_64/lib/cmake -DCMAKE_BUILD_TYPE=Release ../Sigil-0.9.6-Code

But look what happens when I try to build sigil. It even gets up to 100% but fails on what seems to be the last part:
