Minimum CMake version?

[urschrei]

We'd like to list a minimum CMake version requirement in https://github.com/georust/proj, but I couldn't find a minimum version in the docs, and I had a build failure earlier using CMake 3.12.x (resolved by updating to 3.23.2).

[rouault]

it's supposed to be 3.9: https://github.com/OSGeo/PROJ/blob/master/CMakeLists.txt#L12

can you paste the failure you got with 3.12 (and the exact CMake version) ?

[urschrei]

I upgraded to 3.23.2 after I googled the error, which was related to

list sub-command REMOVE_ITEM requires two or more arguments.

Let me see if I can downgrade and reproduce it.

ah this is probably a duplicate of #3087 that affected the 9.0 release. It will be fixed in 9.0.1

[rouault]

closing as a duplicate of #3083 actually.

Ah, that looks like it. Thanks!
