compilation avec CMake

Bonjour,
j'essai de compiler l'exemple de la bibliotheque libdash avec le systéme de construction de logicielles CMake(je travaille sur ubuntu 12.04 LTS 64 bits) ,le dossier de l'exemple contient  le fichier CMakeLists.txt donc je suis placé dans ce dossier et et j'ai ercit la ligne de commande suivante:

cmake . -G"Unix Makefiles"

cette insrtuction affiche le msg suivant:

et je ne trouve pas le fichier Makefile alors quand j'ai ecrit la ligne de commande:

make

je trouve :
(make: *** Pas de cibles spécifiées et aucun makefile n'a été trouvé. Arrêt.).

est-ce quelqu'un peut m'aider svp

Merci

Salut,

Il serait peut-être bon de commencer par lire les messages d’erreurs, non ?

Re : compilation avec CMake

oui j'ai installé les bibliothéque manquante:

aptitude install libavdevice-dev
aptitude install libavcodec-dev
aptitude install libavfilter-dev 
aptitude install libavswacale-dev

et je trouve le makefile mais lorsque je compile avec la commande:

make

je trouve un erreur:
