It succeeds with GCC 12.3.0, but fails with GCC 13.2.0 and 14.0.1 (dev). I thought It is some issues with paralled building, but It fails when using a single job!

[MehdiChinoune]

Actually It's because of Ninja generator!

Ah - good. I finally had a successful build with 13.2 a couple of weeks ago, but did not have any build issues. Just some run-time issues where F2008 polymorphic assignment had to be reverted to F2003 ALLOCATE statements. (And even that was only in some of the pFUnit dependencies I think.

Cheers.

[MehdiChinoune]

We have reported the issue to CMake, they say that pFUnit should use target_link_libraries() instead of add_dependencies() if there is a module dependency. see: https://gitlab.kitware.com/cmake/cmake/-/issues/25788#note_1497239

I could open a PR if there is no required CLA.

[tclune]

Please do. I've given up on the CLA.
