Build fails on Ubuntu 16.04

I tried building on Ubuntu 16.04 using ninja and it failed with the following error:

CMake Error at tools/clif/backend/CMakeLists.txt:15 (include_directories):
  include_directories given empty-string as include directory.

I installed protobuf from source following the directions here.

Here’s the output from the full run:

@gpshead Gotcha - thanks for looking into it for me. I think your assessment is correct. For completeness, here’s the output @mrovner asked for:

kkiningh@mew:~$ pkg-config --cflags-only-I protobuf

kkiningh@mew:~$ cat /usr/lib/pkgconfig/protobuf.pc
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: Protocol Buffers
Description: Google's Data Interchange Format
Version: 3.3.0
Libs: -L${libdir} -lprotobuf -pthread  -lpthread
Libs.private: -lz
Cflags: -I${includedir} -pthread
Conflicts: protobuf-lite

Also, for anyone who comes across this thread later, I was able to workaround this by commenting out lines containing “{GOOGLE_PROTOBUF_INCLUDE_DIRS}” in the relevant CMakeLists.txt (specifically, lines 33 and 37 in tools/clif/backend/CMakeLists.txt).
