This is the output of cmake on Ubuntu 18.04 with cmake 3.10.2, trying to build git 347dab9504ab822315e3bb07b13473ea1fd579fe:

It is working fine with cmake 3.16.3 on Ubuntu 20.04.

Thank you for reporting this!

This should be fixed with commit b42f531d which restores compatibility with CMake versions down to 3.0.0.

LaHaine commented 2 years ago

Indeed, it is fixed, thanks.

The fix is included in MP4v2 v2.1.2 released just now.
