+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.
