As explained by @detrick, the Ubuntu package libgtest-dev only installs sources, so you need to build and install the libraries yourself.

However, there is a much simpler way for building and installing since Ubuntu 18.04 than the manual commands in other answers:

sudo apt install libgtest-dev build-essential cmake
cd /usr/src/googletest
sudo cmake .
sudo cmake --build . --target install
