This applies the same fix that D84748 did for macro definitions. Appropriate include path is now automatically set for all libraries which link against gtest targets, which avoids the need to set include_directories in various parts of the project.

# 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'.
