Good afternoon,
I am trying to create a repository that will build and install `Mesa 3D` in a local directory. I have read that `Mesa 3D` needs to be configured using `Meson` but I would like _both_ of these downloaded and built in the local directory of my repository. I am using `CMake 3.22` and `ninja` instead of `make`.
I think the way to accomplish this would be to use `CPMAddPackage` or `ExternalProject_Add` (I am not picky) ?
I have been going around with this for a few days and am hoping one of you **CMake** experts has some direction to point me to. I am hoping there is a _single_ **CMakeLists.txt** file that I could create that could do this so that all I would need to do is run something like the following in the current directory of the local directory I am building:
```auto
$ mkdir build && cd build
$ cmake -GNinja ../
```
Thank you in advance for any help.

In general that command sequence isn’t necessary for CMake projects. Just
```auto
cmake -GNinja -Bbuild
```
Is equivalent.
You could define external project using meson for mesa. First using find\_package(Python) and execute\_command to pip install meson.

It’s not trivial to extract, but Mesa and Meson are part of the [common-superbuild](https://gitlab.kitware.com/paraview/common-superbuild/) which relies on `ExternalProject_Add` under the hood. The quick thing to do would be to just take the logic around `superbuild_add_project`, replace that call with `ExternalProject_Add` and include the relevant bits from `versions.cmake` then tweak from there. Other bits may break, but maybe you don’t need them (the superbuild does…other things to do some package management stuff).

Thank you @scivision and @ben.boeckel for the replys.
It sounds like common-superbuild might be what I am looking for.
Please excuse an ignorant question, @ben.boeckel , but can you tell me where the `superbuild_add_project` call is located?

Look under the `projects/` directory for `meson.cmake` and `*mesa*.cmake`.
