1 # A sample Makefile for building Google Test and using it in user
2 # tests. Please tweak it to suit your environment and project. You
3 # may want to move it to your project's root directory.
7 # make [all] - makes everything.
8 # make TARGET - makes the given target.
9 # make clean - removes all files generated by make.
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.
15 # Points to the root of Google Test, relative to where this file is.

19 # Where to find user code.

23 # Set Google Test's header directory as a system directory, such that
24 # the compiler doesn't generate warnings in Google Test headers.
