gtest_demo

Integration of the google test framework(gtest) with existing project using cmake build system

Method 1

To run the google test successfully, install the google test on you system. For example on ubuntu machine it can be done as follows:

$sudo apt-get install libgtest-dev

However, this won't install the needed libraries. It only copies the source files that needs to be build. So navigae to /usr/src/gtest:

$cd /usr/src/gtest

Create and build directory and compile the source:

$mkdir build && cd build && cmake ..

Then run the make file:

$sudo make

Finally, copy the recently built static libraries to the /usr/lib so that the application finds it easily:

sudo cp *.a /usr/lib

Makefile integration

Then provide the include and link path as follows in your Makefile:

GTEST_INCLUDES=-I/usr/include/gtest

GTEST_LIBS=-pthread -lgtest

LIBRARY_INCLUDES=-L/usr/lib

Then link the libraries:

`$ g++ $(GTEST_INCLUDES) $(LIBRARY_INCLUDES) test.cpp $(GTEST_LIBS) -o tester

CMake integration

See the CMakeLists.txt in project's root.

Method 2

In this method, you don't need to install the gtest library on your system. You can include the gtest into your project using git submodule. TODO: More flexible integration of gtest into existing system.
