Compiling and linking Google Tests from command line

Some homework for me on how best to incorporate Google Tests to unit test my own libraries without bringing in the whole JVM as a dependency.

The main thing is to incorporate my build framework to build the gtest libraries, to link my code, the unit tests code, and the library together.

The raw, rudimentary command line to do so with the samples given is as such:

g++ -Wl,-rpath=\$ORIGIN -Iinclude -L. -lgtest -lgtest_main \
    samples/ \

The gtest_main provides the main() function, and gtest provides the test routines.
