# 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'.
