# Experimental CMake build script for Google Test.
#
# Consider this a prototype. It will change drastically. For now,
# this is only for people on the cutting edge.
#
# To run the tests for Google Test itself on Linux, use 'make test' or
# ctest. You can select which tests to run using 'ctest -R regex'.
# For more options, run 'ctest --help'.
