      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.
      4 #
      5 # 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.
     14 
     15 # Points to the root of Google Test, relative to where this file is.
     16 # Remember to tweak this if you move this file.
