How to use aGrUM with CMake

As a build system, aGrUM uses CMake (http://www.cmake.org). A minimal project with agrum should look like this (for a project foo):

• in the project folder, a sub-folder src,
• in src folder, your *.{cpp|h|etc.} files
• in src folder, a file named CMakeLists.txt like this one :

project(FOO)
cmake_minimum_required(VERSION 2.8)
# classical options 
# -DCMAKE_BUILD_TYPE=Debug|Release 
# -G "MinGW Makefiles" 
# -G "Visual Studio 16 2019" -A x64
#
# cmake -DCMAKE_BUILD_TYPE=Debug -G "Visual Studio 16 2019" -A x64
# or
# cmake -DCMAKE_BUILD_TYPE=Release -G "Visual Studio 16 2019" -A x64

set (CMAKE_CXX_STANDARD 14)

find_package(OpenMP)
if (OPENMP_FOUND)
  set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
  set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
  set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
endif()

# do not forget to change this line if needed ("act install -d/folder/install/agrum.")
set(AGRUM_INSTALLATION_DIRECTORY "/folder/install/agrum")

set(aGrUM_DIR "${AGRUM_INSTALLATION_DIRECTORY}/lib/cmake/aGrUM/")
find_package(aGrUM)

if (aGrUM_FOUND)
  include(${AGRUM_USE_FILE})
else (aGrUM_FOUND)
  message(FATAL_ERROR "Please install aGrUM")
endif (aGrUM_FOUND)

file(GLOB FOO_SOURCE ${FOO_SOURCE_DIR}/*.cpp)
file(GLOB FOO_INCLUDE ${FOO_SOURCE_DIR}/*.h)

add_executable (foo ${FOO_SOURCE})
target_link_libraries(foo agrum)

 * 

• a small minimum src/FOO.cpp :

  #include <iostream>
  
  #include <agrum/tools/core/hashTable.h>
  
  int main() {
    gum::HashTable<std::string,int> h;
  
    h.insert("Hello",1);
    h.insert("World",2);
  
    std::cout<<h<<std::endl;
  }

• to compile the project (from the project folder)

mkdir build
cd build
cmake ../src/
make

• build/foo is the executable.
