# A sample Makefile for building Google Test and using it in user
|
| 2 |

|
# tests. Please tweak it to suit your environment and project. You

# SYNOPSIS:
|
| 6 |
|
|
#
|
| 7 |
|
|
# make [all] - makes everything.
|
| 8 |
|
|
# make TARGET - makes the given target.
|
| 9 |
|
|
# make clean - removes all files generated by make.
|
| 10 |
|
|
|
| 11 |
|
|
# Please tweak the following variable definitions as needed by your
|
| 12 |
|
|
# project, except GTEST_HEADERS, which you can use in your own targets
|
| 13 |
|
|
# but shouldn't modify.
