Given the source and the Makefile.in, programmer instinctively opened a terminal and now wrote: It is the responsibility of the configure script to take the Makfile.in and produce a customized Makefile specific to the system. They applied the fundamental theorem of Software Engineering and introduced the extra level of indirection – Makefile.in Programmers being programmers wanted these customizations to be done automatically. The Makefile had to be customized specific to the system. Programmers wanted to compile the same source across these diverse systems but the Makefile was a constraint. Enter ConfigureĪs times went by systems started to get diverse. The system worked flawlessly because it was built by programmers to be used by programmers. Failure mostly meant fixing compilation errors which programmers were adept at anyway. Success meant the program or library was immediately available for use. Given the source and the Makefile, programmer instinctively opened a terminal and wrote: Hence it was easy for programmers to create a Makefile, define the standard targets and expect Make to take care of the rest. Every self-respecting Unix system had a version of Make bundled with it. Passed 0.“Those who cannot remember the past are condemned to repeat it.”Īny library or executable that was made compiling more than a couple of source files involved Make. my_project/buildġ/1 Test #1: HelloTest.BasicAssertions. The CXX compiler identification is GNU 10.2.1 The C compiler identification is GNU 10.2.1 Now you can build and run your test: my_project$ cmake -S. Last two lines enable CMake’s test runner to discover the tests included in the You want to build ( hello_test), and links it to GoogleTest ( gtest_main). The above configuration enables testing in CMake, declares the C++ test binary ) include (GoogleTest ) gtest_discover_tests (hello_test ) With GoogleTest declared as a dependency, you can use GoogleTest code withinĪs an example, create a file named hello_ in your my_project Hash often to point to the latest version.įor more information about how to create CMakeLists.txt files, see the The Git commit hash of the GoogleTest version to use we recommend updating the The above configuration declares a dependency on GoogleTest which is downloadedįrom GitHub. ) # For Windows: Prevent overriding the parent project's compiler/linker settings set (gtest_force_shared_crt ON CACHE BOOL "" FORCE ) FetchContent_MakeAvailable (googletest ) You’ll use this file to set up your project and declare a dependency onįirst, create a directory for your project:Ĭmake_minimum_required (VERSION 3.14 ) project (my_project ) # GoogleTest requires at least C++14 set (CMAKE_CXX_STANDARD 14 ) include (FetchContent ) FetchContent_Declare ( Set up a projectĬMake uses a file named CMakeLists.txt to configure the build system for a Note: The terminal commands in this tutorial show a Unix shell prompt, but theĬommands work on the Windows command line as well.
