Nana CMake file for Ubuntu

Nana is a "cross-platform library for GUI programming in modern C++ style". More information is available on this website http://nanapro.org/en-us/.

I wanted to use this library with a simple C++ application on Ubuntu. So I created a CMake project with the following folders (see the screenshot below).

Following the getting started and installation instructions here http://nanapro.org/en-us/blog/2016/05/an-introduction-to-nana-c-library/, I downloaded the nana source files, placed them under the nana folder and compiled them into the static library libnana.a.

Next, I created a simple Hello World C++ source file and placed under the src folder.

I then created a CMakeLists.txt file that describes the project and dependencies.

cmake_minimum_required(VERSION 2.8.6)
project(runnana)

find_package (Threads REQUIRED)
find_package (X11 REQUIRED)
find_package(Freetype REQUIRED)

set (CMAKE_BUILD_TYPE Debug)
set (LIBRARY_OUTPUT_PATH bin)

set (CMAKE_CXX_STANDARD 14)
set (CMAKE_CXX_STANDARD_REQUIRED ON)

set (CMAKE_ARCHIVE_OUTPUT_DIRECTORY ./bin)
set (CMAKE_LIBRARY_OUTPUT_DIRECTORY ./bin)
set (CMAKE_RUNTIME_OUTPUT_DIRECTORY ./bin)

set (NANA_INCLUDE nana/include)
set (NANA_LINK nana/build/bin)

include_directories (
 ${FREETYPE_INCLUDE_DIRS}
 ${X11_INCLUDE_DIR}
 ${NANA_INCLUDE}
)
link_directories (
 ${NANA_LINK}
)
set (RUNNANA_LINK_LIBS
 stdc++fs
 nana
 ${X11_LIBRARIES}
 ${CMAKE_THREAD_LIBS_INIT}
 rt
 Xft
 png
 asound
 fontconfig
 ${FREETYPE_LIBRARIES}
)
set (RUNNANA_INCLUDE
 include
)

file (GLOB RUNNANA_SOURCES "src/*.c*")
add_executable (runnana ${RUNNANA_SOURCES})
target_include_directories (runnana PUBLIC ${RUNNANA_INCLUDE})
target_link_libraries (runnana ${RUNNANA_LINK_LIBS} stdc++fs)

Using this CMake file, I can easily build the project and compile the simple hello world executable, as shown below.
