Hi, I am new to cmake and really hope am doing this correctly. I asked stackoverflow but didn't get a good enough answer for my specific problem here;
If I want root/sub-directories/ as separate sub-projects that can be compiled using the individualCMakeLists.txts in their folders I find myself literally copy pasting almost the entire root file CMakeLists.txt per sub-directory. I was wondering if there is a better way to have a main project and then sub-projects that get the shared dependencies from main project and can be compiled without cmake-ing the root CMakeLists.txt. My directory structure is; CMakeLists.txt (root project) | __ sub_dir-1 | __ | __ CMakeLists.txt (sub-project) | __ sub_dir-2 | __ | __ CMakeLists.txt (sub-project) | __ sub_dir-3 | __ | __ CMakeLists.txt (sub-project) ... Essentially, I want to be able to: 1. cmake root/CMakeLists.txt, which creates an entire project that includes the sub-projects (I already have this implemented using individual CMakeLists.txts inside sub-directories. 2. cmake root/sub-dir/CMakeLists.txt and only compile the sub-project, which essentially also finds the necessary dependencies and includes them from maybe .cmake includes or root/CMakeLists.txt. What is the best way to approach this structure; while retaining the first bullet point of having the ability to compile it as an entire project. And also not crowding the sub-dir/CMakeLists.txt too much with redundant code? Appreciate any suggestions! Thank you. -- Muhammad Osama
