CMake和find_package问题

Question

I'm very new to CMake, and I try to write a CMake file for my project. My project consists of .h and .cpp files, generating an executable, and using the SFML library. I've installed the findSFML script, I use the find_package function of CMake:

cmake_minimum_required(VERSION 2.6)

# Projet name
project("Witch_Blast")

file(
        GLOB_RECURSE
        source_files
        src/*
)

add_executable(
        "Witch_Blast"
    ${source_files}
)

# Detect and add SFML
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})
find_package(SFML 2.1 REQUIRED system window graphics audio)
target_link_libraries(Witch_Blast ${SFML_LIBRARIES})

I try to generate a Windows Code::Blocks project. It finds the library and generate projects files.

My problem: It won't compile because it won't find the SFML header files, and I cannot modify the project setting...

What have I done wrong ?

Thanks !

(But it's not a linker error, it's an include path error)

Answer 1

You need to add the header directory to you compiler's path.

include_directories(${SFML_INCLUDE_DIR})

All variables find_package(SFML) sets can be found here .
