Use of precompiled libgtest Not Recommended
	-------------------------------------------

The Google C++ Testing Framework uses conditional compilation for some
things.  Because of the C++ "One Definition Rule", gtest and gmock
must be compiled with exactly the same flags as your C++ code under
test.  Because this is hard to manage, upstream no longer recommends
using precompiled libraries [1].


	Using GTest with your project
	-----------------------------

See the upstream README for instructions on using gtest with your
project.  The sources for libgtest are installed into
/usr/src/googletest/googletest along with CMakeLists.txt for use with
cmake.

If your build system uses CMake, the ExternalProject command can be
used to build gtest, then FindGTest can be used to find the built
library.


	Using gmock with your project
	-----------------------------

See the upstream README for instructions on using gmock with your
project.  The sources for libgmock are installed into
/usr/src/googletest/googlemock along with CMakeLists.txt for use with
cmake.

With this Debian package something like the following should be enough to build 
a static library (which also includes gtest):

g++ -I/usr/src/googletest/googlemock -c /usr/src/googletest/googlemock/src/gmock-all.cc
g++ -I/usr/src/googletest/googletest -c /usr/src/googletest/googletest/src/gtest-all.cc
ar -rv libgmock.a gmock-all.o gtest-all.o
