# Defines functions and macros useful for building Google Test and |

# Google Mock. |

# |

# Note: |
|
# |
|
# - This file will be run twice when building Google Mock (once via |
|
# Google Test's CMakeLists.txt, and once via Google Mock's). |
|
# Therefore it shouldn't have any side effects other than defining |
|
# the functions and macros. |
|
# |
|
# - The functions/macros defined in this file may depend on Google |
|
# Test and Google Mock's option() definitions, and thus must be |
|
# called *after* the options have been defined. |
|

|
# Tweaks CMake's default compiler/linker settings to suit Google Test's needs. |

|
# This must be a macro(), as inside a function string() can only |
|
# update variables in the function scope. |
