What is this? This is an example setup of cmake with google test. I got it working after consulting the google test primer, among other things. Hopefully it'll help someone get set up with C++ and google test.
Where are things? build/ is where code is built - like where executables are. lib/ includes gtest-1.6.0. Rest of code in root: -CMakeLists.txt must be in each subdirectory of the project -main.cpp is just a driver file - the common place to run the normal application -project1.cpp and project1.h have code for the class 'Project1' -test_project1.cpp has code to test Project1
What do I do? Use cmake and make If you want to test it all out through the common gtest procedure, first delete build/ (if present). Then...
In the project root:
mkdir build cd build cmake .. By now Makefiles should be created. Then, to build executables and do all that linking stuff,
make To prepare all your tests, run this:
cmake -Dtest=ON .. To run all tests easily,
make test Run executables Then you can do ./myexecutable for the generated executable, e.g.:
./project1 and if you did cmake with test=ON:
./runUnitTests Details Command things cmake -Dtest=ON turns on the variable 'test', which is specified in the root CMakeLists.txt file. This is handy if you want to build in certain ways. Clear description here.
My experience I spent a lot of time figuring out how I wanted to reference the gtest library.
On StackOverflow there are ways to download the svn repo when you cmake, but that's internet connection dependent. There is also a way to set a variable for where gtest is installed on your system, but that got a bit tedious.
In the end I opted to just have a copy of gtest locally in whatever application I have that uses gtest. This user's edited solution and my own question's response helped me out.
