CMake and including other makefiles

Question

Lets say I have a CMakeLists.txt and I want to call another include another makefile in that file (similar to the #include syntax in C), how would I accomplish this?

Answer 1

From the CMake documentation:

• include: Read CMake listfile code from the given file.

  include(<file|module> [OPTIONAL] [RESULT_VARIABLE <VAR>]
                      [NO_POLICY_SCOPE])
  

Example use:

CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)
include (Project.txt)

Project.txt:

project (Project)
add_executable(Project project.c)
