help with cmake?

[Little Bobby Tables]

so if anyone remembers, im writing an irc bot. the source is getting pretty large, so i thought i would write a makefile. the only problem is, its getting quite big, so i turned to cmake to generate them. i have a good CMakeLists.txt file going, but i cant figure out how to do something. it links to sfml-system and sfml-network, but i cant figure out how to get cmake to look for those libraries. any help?

I thought Cmake ran off your computer's paths and settings of the person compiling. I've never used it personally though.

You can use the findSFML.cmake script in SFML root/cmake/modules then in CMakeLists.txt add something like:

find_package(SFML 2 REQUIRED network system)
if(SFML_FOUND)
    include_directories(${SFML_INCLUDE_DIR})
    link_directories(${SFML_ROOT}/lib)
else()
    message(FATAL_ERROR "SFML not found by find_package. Try specifying SFML_ROOT")
endif()

do i have to copy it into my projects folder that contains the List file?

[naraku9333]

It doesn't really matter where you copy it to, you just need to add the path to CMAKE_MODULE_PATH

[Little Bobby Tables]

a) i cant find the findSFML script
b) is that an environment variable or would i have to add it in my cmakeLists file

[naraku9333]

a) On linux it might be in /usr/share/SFML or /usr/local/share/SFML
b) Its a cmake variable, its already defined you just need to add your module directory

set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})

EDIT: If you still can't find findSFML.cmake its also here https://github.com/LaurentGomila/SFML/blob/master/cmake/Modules/FindSFML.cmake

thanks! that worked great. just one last problem... ive tried googling it, but i cant find anything about this, and its generating lots of linker errors. so i have file foo.cpp and file bar.cpp (just an example). main.cpp uses both of those. how would i tell cmake to link to those? they are all in the same folder

[naraku9333]

Try

file(GLOB_RECURSE SOURCE "${SOURCE_DIR}*.cpp")

then

add_executable (ircbot ${SOURCE})
