+## Integration as external CMake project
+
+Sometimes you want to use CppUTest in your project without installing it to your system or for having control over the version you are using. This little snippet get the wanted version from Github and builds it as a library.
+
+```cmake
+# CppUTest
+include(FetchContent)
+FetchContent_Declare(
+    CppUTest
+    GIT_REPOSITORY https://github.com/cpputest/cpputest.git
+    GIT_TAG        v3.8
+)
+# Set this to ON if you want to have the CppUTests in your project as well.
+set(TESTS OFF CACHE BOOL "Switch off CppUTest Test build")
+FetchContent_MakeAvailable(CppUTest)
+include_directories(${CppUTest_SOURCE_DIR}/include)
+```
 
+It can be used then like so:
 
+```cmake
+file(GLOB_RECURSE TEST_SOURCES ${TEST_DIR}/*.cpp)
+add_executable(run_tests ${TEST_SOURCES})
+target_link_libraries(run_tests CppUTest)
+```
