Subject: [PATCH 3/3] build: Prefer googletest from the system.
Fixes issue #4.
The build system now look for a system installed googletest or falls
back to the bundled copy of googletest otherwise.
* CMakeLists.txt: Add call to find_package(GTest).
(include_directories): Remove "src/googletest/googletest/include" from
arg.
* src/CMakeLists.txt[NOT GTEST_FOUND]: Define the gtest and gtest_main
libraries when GTEST_FOUND is false. Globally include the googletest
headers here. Define aliases for the gtest and gtest_main libraries
that match those defined by the FindGTest module.
* src/tests/CMakeLists.txt: Replace references to gtest_main and gtest
by GTest::Main and GTest::GTest, respectively.
