CMake - Automatically add all files in a folder to a target?

Question

I am considering switching a cross platform project from separate build management systems in Visual C++, XCode and makefiles to CMake.

One essential feature I need is to add automatically all files in a directory to a target. While this is easy to do with make, it is not easily doable with Visual C++ and XCode (correct me if I am wrong). Is it possible to do it in directly in CMake? How?

Feel free to add any other thing I should be aware of before going to learn CMake, considering that currently the project is mid-sized (8 libraries, 2 executables, 8 test projects and it is depending on about 8 external libs).

Answer 1

It is possible. E.g. with file(GLOB:

cmake_minimum_required(VERSION 2.8)

file(GLOB helloworld_SRC
    "*.h"
    "*.cpp"
)

add_executable(helloworld ${helloworld_SRC})
