# Compile everything with C++11 and with debug flags
SET (CMAKE_CXX_STANDARD 11)
SET (CMAKE_CXX_STANDARD_REQUIRED ON)
SET (CMAKE_CXX_EXTENSIONS OFF)

# Also make sure we link with the threads library in question
FIND_PACKAGE (Threads)

# Source files need to know where headers are:
INCLUDE_DIRECTORIES(include ${CMAKE_BINARY_DIR}/include)

# Set paths correctly to take BOOST from wherever it is
# installed on the current system
FIND_PACKAGE(Boost REQUIRED COMPONENTS system)
