CPP Build Systems & Package Management 2

Question 1

In CMake, what does the `target_include_directories` command's `PUBLIC` keyword signify?

Accepted Answer

Directories are added to the target and any target that links to it

Answer

PUBLIC means the include directories apply both to the target itself and to any downstream targets that link against it.

Question 2

Which CMake generator is commonly used to produce Ninja build files?

Accepted Answer

-G "Ninja"

Answer

The `-G "Ninja"` flag tells CMake to generate Ninja build files instead of Makefiles.

Question 3

What is the purpose of `vcpkg integrate install` on Windows?

Accepted Answer

Makes vcpkg libraries automatically available to MSBuild and Visual Studio projects

Answer

`vcpkg integrate install` wires vcpkg into MSBuild so installed libraries are found automatically in Visual Studio.

Question 4

In a Makefile, what does the special target `.PHONY` accomplish?

Accepted Answer

Declares targets that are not actual files, preventing conflicts with same-named files

Answer

`.PHONY` tells make that a target name is a label for a recipe, not a real file, so it always runs.

Question 5

Which CMake command sets a compile definition only for a specific target without affecting others?

Accepted Answer

target_compile_definitions()

Answer

`target_compile_definitions()` scopes preprocessor definitions to a single named target.
