cmake

Hard link the cmake_commands.json file generated after running cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1 .. in the build directory.

Set up the dir tree as follows:

___ root
 |
 |--- build # artifacts go here
 |--- src # source files, including main go here
 |--- include # header files go here
 |--- libs # library dependencies go here
 |--- .git # no shit
 .gitgnore # add build to this

CMakeLists.txt at root:

cmake_minimum_required(VERSION 3.27)

project(tic_tac_toe
    VERSION 0.1
    DESCRIPTION "Learning CMake and FXTUI together"
    LANGUAGES CXX
)
# CMAKE Standard
set (CMAKE_CXX_STANDARD 17)
# Adding global flags
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wextra -Wpedantic")
include(FetchContent)

FetchContent_Declare(ftxui

FetchContent_GetProperties(ftxui)
if(NOT ftxui_POPULATED)
  FetchContent_Populate(ftxui)
  add_subdirectory(${ftxui_SOURCE_DIR} ${ftxui_BINARY_DIR} EXCLUDE_FROM_ALL)
endif()
# including the header files
include_directories(include)
# including the source files
add_subdirectory(src)

CMakeLists.txt at src:

set (TARGET ${PROJECT_NAME})
file(GLOB SRC_LIST CONFIGURE_DEPENDS "${CMAKE_SOURCE_DIR}/src/*.cpp")
add_executable(${TARGET} ${SRC_LIST})
target_link_libraries(${TARGET}
  PRIVATE ftxui::screen
  PRIVATE ftxui::dom
  PRIVATE ftxui::component
)

CMakeLists.txt at libs:

# Note that headers are optional, and do not affect add_library, but they will not

file(GLOB LIB_HEADER_LIST CONFIGURE_DEPENDS "${ModernCMakeExample_SOURCE_DIR}/libs/*.cpp")
file(GLOB LIB_SRC_LIST CONFIGURE_DEPENDS "${ModernCMakeExample_SOURCE_DIR}/libs/src/*.cpp")

# Make an automatic library - will be static or dynamic based on user setting
add_library(modern_library ${LIB_SRC_LIST} ${LIB_HEADER_LIST})

# We need this directory, and users of our library will need it too
target_include_directories(modern_library PUBLIC ../libs)

# This depends on (header only) boost
target_link_libraries(modern_library PRIVATE Boost::boost)

# All users of this library will need at least C++17
target_compile_features(modern_library PUBLIC cxx_std_17)

.gitignore contains /build* and .cache

Might have to add libs separately later on. Not sure how to do that.
