cmake-module-submodule.cmake

A cmake module taking care of a project's git submodules (and checking out specific commits/tags)

PREREQUISITES

cmake
already added git submodules (preferably in vendor/ but you can set this to another direcotory inside submodules.cmake)
adjust submodules.cmake to the git submodules you have added to your repo:
- in this example I am using two submodules under vendor/serialization, and vendor/testing respectively.

Include submodules.cmake in your main CMakeLists.txt file:

include(cmake/submodules.cmake)

Then run cmake as usual from the out-of-source build-directory:

build$ cmake ..
