[PROJ] Trouble building packages for distribution

[Kristian Evers]

I’m in the process of preparing 9.8.0RC1 but seem to have hit a bit of an issue with CMake that I can’t make sense of.
In short, empty archives are produced when running "cmake --build . --target dist”.

As usual I follow the recipe in HOWTO-RELEASE:

$ BRANCH_NAME=9.8
$ git clone --depth 1 --branch $BRANCH_NAME https://github.com/OSGeo/PROJ.git PROJ-$BRANCH_NAME
$ cd PROJ-$BRANCH_NAME
$ mkdir _build && cd _build
$ cmake -D BUILD_TESTING=OFF ..
$ cmake --build . --target dist

Looking at the produced files shows they are empty:

$ ls -lh proj-9.8.0*
-rw-r--r--  1 kevers  staff    29B Feb 23 16:31 proj-9.8.0.tar.gz
-rw-r--r--  1 kevers  staff    22B Feb 23 16:31 proj-9.8.0.zip

Oddly enough, if I do a similar thing within my git repo I succeed:

$ mkdir build && cd build
$ cmake -D BUILD_TESTING=OFF ..
$ cmake --build . --target dist
$ ls -lh proj-*
-rw-r--r--  1 kevers  staff   6.4M Feb 23 16:38 proj-9.8.0.tar.gz
-rw-r--r--  1 kevers  staff   6.9M Feb 23 16:38 proj-9.8.0.zip

I see that a few things have changed in CMakeLists.txt but nothing that seems related. Could someone try to reproduce this?
