Lets abstract some configuration of our project to a user defined Config.cmake file.
Let's assume your project uses CMake and has a directory structure similar to the one shown below
The Config.cmake file has the following stuff -
set_target_properties(
${CMAKE_PROJECT_NAME}
PROPERTIES CXX_STANDARD 17
CXX_STANDARD_REQUIRED YES
CXX_EXTENSIONS NO)
include(CheckIPOSupported)
check_ipo_supported(RESULT result)
if(result)
set_target_properties(${CMAKE_PROJECT_NAME}
PROPERTIES INTERPROCEDURAL_OPTIMIZATION TRUE)
endif()
find_program(CCACHE_PROGRAM ccache)
if(CCACHE_PROGRAM)
set(CMAKE_CXX_COMPILER_LAUNCHER "${CCACHE_PROGRAM}")
set(CMAKE_CUDA_COMPILER_LAUNCHER "${CCACHE_PROGRAM}") # CMake 3.9+
endif()
Then, in our root CMakeLists.txt file, lets add the following lines -
list(APPEND CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/cmake/Modules")
This line must go after your
projectconfiguration
And finally,
include(Config)
Where Config is the name of file with our abstractions
