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)

set (CMAKE_CXX_STANDARD 14)

# do not forget to change this line if needed ("act install -d...")
set(AGRUM_INSTALLATION_DIRECTORY "/home/phw/usr")
set(aGrUM_DIR "${AGRUM_INSTALLATION_DIRECTORY}/lib/cmake/aGrUM/")

find_package(aGrUM)

if (aGrUM_FOUND)
  include_directories(${AGRUM_INCLUDE_DIR})
  link_directories(${AGRUM_LIB_DIR})
else (aGrUM_FOUND)
  message(FATAL_ERROR "Please install aGrUM")
endif (aGrUM_FOUND)

# cmake -DCMAKE_BUILD_TYPE=DEBUG
# or
# cmake -DCMAKE_BUILD_TYPE=RELEASE
#     RELEASE is the default option (thanks to the next 3 lines)
if( NOT CMAKE_BUILD_TYPE )
  set( CMAKE_BUILD_TYPE RELEASE)
endif()

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

add_executable (foo ${FOO_SOURCE})

if (${CMAKE_BUILD_TYPE}  STREQUAL "RELEASE") # release : act install release
  target_link_libraries(foo agrum)
else() # debug : act install debug
  target_link_libraries(foo agrum-dbg)
endif()
 * 

• a small minimum src/example.cpp :

  #include <iostream>
  
  #include <agrum/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.
