erreurs lors de la compilation de 3.0.0

[darkshot]

Bonjour, je tente vainement d'installer darktable 3.0

Voilà ce qui se passe:

Code :

~/darktable-3.0.0$ ./build.sh
Darktable build script

Building directory:  /home/regis/darktable-3.0.0/build
Installation prefix: /opt/darktable
Build type:          RelWithDebInfo
Build generator:     Unix Makefiles
Build tasks:         4


CMake Deprecation Warning at CMakeLists.txt:5 (cmake_policy):
 The OLD behavior for policy CMP0048 will be removed from a future version
 of CMake.

 The cmake-policies(7) manual explains that the OLD behaviors of all
 policies are deprecated and that a policy should be set to OLD only under
 specific short-term circumstances.  Projects should be ported to the NEW
 behavior and not rely on setting a policy to OLD.

Je ne suis pas un grand expert de compilation.

Avant de faire des dégâts, quelqu'un pourrait-il me donner un coup de main? D'avance merci et joyeux fêtes à tous!
