GTest compile error during workspace build

edit

Trying to build my workspace using

sudo ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release --install-space /opt/ros/kinetic

but I keep getting the following error while it's building camera_info_manager:

<== Failed to process package 'camera_info_manager':

Reproduce this error by running:
==> cd /home/pi/catkin_ws/build_isolated/camera_info_manager && /opt/ros/kinetic/env.sh make -j4 -l4

Command failed, exiting.

What is strange to me is that it looks like the problems are all contained within gtest. I can't find anything relevant, but I tried installing gtest from source as opposed to from the binaries and it still had no change (even with compiling with C++11).

EDIT:

In camera_info_manager's CMakeLists.txt, gtest isn't in the two first find_package calls:

find_package(catkin REQUIRED COMPONENTS camera_calibration_parsers image_transport roscpp roslib sensor_msgs)

and

find_package(Boost)

I did find gtest in this conditional, however:

if(CATKIN_ENABLE_TESTING)
  find_package(rostest)
  # Unit test uses gtest, but needs rostest to create a ROS environment.
  # Hence ...
