Comment faire pour inclure CGAL dans le projet CLion/Linux

Question

Je suis relativement nouveau dans C++ Cmake et Clion et j'ai eu du mal à installer CGAL pour mon projet sous Clion (que je tourne sur Ubuntu Gnome). Je n'ai pas pu trouver des problèmes similaires ici ou ailleurs et j'ai été bloqué pendant plus d'une semaine maintenant, donc j'apprécierais beaucoup de l'aide.

J'ai installé CGI Cmake GUI, exécutez make et l'installation. Avec la CMakeList.txt suivante à Clion:

cmake_minimum_required(VERSION 3.5) 
project(AGRAN) 

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -frounding-math") 

find_package(OpenCV REQUIRED) 
include_directories(${OpenCV_INCLUDE_DIRS}) 
set(LIBS ${LIBS} ${OpenCV_LIBRARIES}) 

find_package(CGAL REQUIRED COMPONENTS Core GMP RS3 MPFI) 
include_directories(${CGAL_INCLUDE_DIRS}) 
set(LIBS ${LIBS} ${CGAL_LIBRARIES}) 

find_package(Boost REQUIRED) 
include_directories(${Boost_INCLUDE_DIRS}) 
set(LIBS ${LIBS} ${Boost_LIBRARIES}) 

set(SOURCE_FILES main.cpp) 
add_executable(AGRAN ${SOURCE_FILES}) 
target_link_libraries(AGRAN ${LIBS}) 

et voici le main.cpp:

#include <iostream> 
#include <CGAL/Nef_polyhedron_3.h> 

using namespace std; 

int main() { 
    cout << "Hello, World!" << endl; 
    return 0; 
} 

CGAL est reckognized par Clion que je peux voir ses fichiers dans les bibliothèques externes/en-tête Chemins de recherche et comme l'auto-complétion identifie les éléments CGAL comme ici Nef_polyhedron_3.h. Pourtant, avec ce simple utilisé include je suis « Build ... ms échoué dans » le journal des événements et les messages construis sorties de fenêtre:

/home/jeremie/CMake/cmake-3.5.2-Linux-x86_64/bin/cmake --build/home/jeremie/.CLion2016.1/system/cmake/generated/AGRAN-39898ace/39898ace/Debug0 --target AGRAN -- -j 8 
[ 50%] Building CXX object CMakeFiles/AGRAN.dir/main.cpp.o 
CMakeFiles/AGRAN.dir/main.cpp.o: In function `CGAL::Interval_nt<false>::Test_runtime_rounding_modes::Test_runtime_rounding_modes()': 
/usr/local/include/CGAL/Interval_nt.h:208: undefined reference to `CGAL::assertion_fail(char const*, char const*, int, char const*)' 
/usr/local/include/CGAL/Interval_nt.h:210 

Après avoir examiné l'intervalle nt.h: 208 je pouvais voir la suivant extrait de code:

typename Interval_nt<>::Internal_protector P; 
CGAL_assertion_msg(-CGAL_IA_MUL(-1.1, 10.1) != CGAL_IA_MUL(1.1, 10.1), 
"Wrong rounding: did you forget the -frounding-math option if you use GCC (or -fp-model strict for Intel)?"); 
CGAL_assertion_msg(-CGAL_IA_DIV(-1., 10) != CGAL_IA_DIV(1., 10), 
"Wrong rounding: did you forget the -frounding-math option if you use GCC (or -fp-model strict for Intel)?"); 
} 

Ce qui est la raison pour laquelle j'ai ajouté -frounding-mathématiques à CMakeLists.txt (sans succès). J'ai également vérifié que CMAKE_CXX_FALGS était -frounding-math dans Cmake lors de la construction de CGAL (voir image).

CMAKE CAPTURE CGAL BUILD CMAKE CXX FLAGS -frounding-math

est ici la sortie make VERBOSE=1 comme suggéré par Marc:

Marc a suggéré le problème provient d'une liaison incorrecte de la bibliothèque illustrée par l'erreur révélant la fonction CGAL::assertion_fail est inaccessible. En effet le drapeau -lCGAL n'est pas visible, serait-ce le problème? qu'est-ce qui devrait être changé pour corriger cela?

Answer 1

Le problème provient d'un fichier CMakeList.txt incorrect. Voici une version qui fonctionne. Merci pour votre aide @MarcGlisse:

cmake_minimum_required(VERSION 3.5) 
project(AGRAN) 

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11") 
find_package(CGAL REQUIRED) 
include(${CGAL_USE_FILE}) 

set(SOURCE_FILES main.cpp) 
add_executable(AGRAN ${SOURCE_FILES}) 
target_link_libraries(AGRAN ${CGAL_LIBS})
