CMake from Zero to Hero

We will shortly go over the project that we will build upon in the next lectures

We see what happens to variables inside subfolders + how to use PARENT_SCOPE

We use functions and target_compiler_options()

We learn what a macro is and how it's different from a function

We treat optional arguments using ARGC, ARGV and ARGN

We use cmake_parse_arguments to make a function with keyword arguments (or named arguments)

We continue our example by reading the version string from the file and setting the output variables

We compare include() with add_subdirectory() and explore some CMake predefined variables, like CMAKE_CURRENT_SOURCE_DIR, CMAKE_CURRENT_LIST_DIR and so on.

We will use install() to copy our header files into the install location

We will call install() with the EXPORT keyword and generate a config file which we later use with find_package

We are creating a small project which uses our old sortdemo project. We call find_package() for that

We will add a namespace to our export, install a binary and play around with CMAKE_PREFIX_PATH. CMAKE_MODULE_PATH is also (very) briefly shown.

We pull GoogleTest with FetchContent to see how to get dependencies with FetchContent

We use pkg-config to find flags that we need to pass to compilers. Next we use pkg-config in CMake to link to the libraries and set include folders.

We demonstrate how to use find_library and find_path

We look at how to write our own find module.

We call find_package with "Threads" to build an example with threads.

We call enable_testing() and add_test() to add some tests in CMake

We customize our tests with set_tests_properties()
