# Build the google test library

# We compile Google Test ourselves instead of using pre-compiled libraries.
# See the Google Test FAQ "Why is it not recommended to install a
# pre-compiled copy of Google Test (for example, into /usr/local)?"
# at http://code.google.com/p/googletest/wiki/FAQ for more details.
