CMake Done Right

1. Why

CMake is indeed not a modern design for package management

find_package(Boost 1.55 COMPONENTS asio)
list(APPEND INCLUDE_DIRS ${BOOST_INCLUDE_DIRS})
list(APPEND LIBRARIES ${BOOST_LIBRARIES})

include_directories(${INCLUDE_DIRS})
link_libraries(${LIBRARIES})

lack of structure
the order of linking is missing

2. Target

Modern CMake is about targets

executable is target
library is target

Properties is the

source file
compiler option
Link against

Properties have two domain

PRIVATE: for internal use
INTERFACE: for usage of this lib

3. Import

When we call find_package(), the CMake would execute FindBoost.cmake and import the Boost::boost, so that we can link them target_link_libraries()

The PAIN: 3rd party dependencies,
