Build only part of a git submodule repository with CMake

I have a C++ project with submodule another_repo:

.
├── CMakeLists.txt
├── ext
│   └── another_repo
│       └── CMakeLists.txt
├── include
└── src

I would like to build only part of another_repo. That said, I need a new, customized CMakeLists.txt to build another_repo, instead of using its original one ./ext/another_repo/CMakeLists.txt.

But how can I do this in the root directory ./CMakeLists.txt?

If you want to build only a part of another_repo then just create a new target which only build the part you want.

For e.g, another_repo has following files:

another_repo/
│── a.cpp
│── b.cpp
│── c.cpp

And you want to build only a.cpp and b.cpp (assuming they don't depend on c.cpp).

In you root directory CMakeLists.txt:

...

set(ANOTHER ext/another_repo)
add_library(part_of_another_repo ${ANOTHER}/a.cpp ${ANOTHER}/b.cpp)
#or add_executable() if it is an executable
...
