Gtest found by catkin, but not compiled

[stonier]

It only gets compiled when you nmake gtest.

Bigger problem - it fails the install if you dont nmake gtests because catkin used EXCLUDE_FROM_ALL on the target.

CMake Error at gtest/cmake_install.cmake:35 (FILE):
  file INSTALL cannot find "C:/work/ws/build/gtest/gtest.dll".
Call Stack (most recent call first):
  cmake_install.cmake:62 (INCLUDE)

NMAKE : fatal error U1077: 'echo' : return code '0x1'
Stop.

Fixed - I was adding the install!
