Hi SFML team and forum readers,
I'm trying to use the new SFML CMake files with minimal success. I have good knowledge of C++, but only working knowledge of CMake. I have a few goals I'm trying to accomplish:
1. Embed SFML in my project (gets compiled as part of project; no separate step)
2. Include SFML statically
3. Expose SFML to other packages (should be a result of 1)
I was able to get the default SFML project building so long as I don't change anything.
However, I want to include SFML in my project, and my current workflow is to call CMake twice - once for SFML, and once for my project. I would like to be able to set up my project such that SFML appears as part of the resultant solution/etc.
My project is set up as follows:
/cmake
| /modules
| | Findimgui.cmake
| | Findimgui-sfml.cmake
| CMakeLists.txt (Main project CMake file)
/intermediate
| /SFML
| SFMLConfig.cmake
| SFMLConfigDependencies.cmake
| ... etc
/third-party
| /SFML
| < basically contents of the SFML GitHub repo; some files/folders get deleted >
/my-project
| ...
I have a Python script to run CMake, the relevant lines are as follows:
run("cmake -A x64 -T host=x64 -DBUILD_SHARED_LIBS=OFF ../../third-party/SFML/", cwd='intermediate/SFML/')
run("cmake -A x64 -T host=x64 -DBUILD_SHARED_LIBS=OFF ../cmake/", cwd='intermediate/')
My main CMakeLists.txt:
cmake_minimum_required(VERSION 3.1)
project(my_proj)
set(my_proj_VERSION_MAJOR 0)
set(my_proj_VERSION_MINOR 1)
set(EXECUTABLE_NAME "my_proj")
set(CMAKE_EXPORT_COMPILE_COMMANDS TRUE)
# Custom packages
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_CURRENT_SOURCE_DIR}/modules/")
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_CURRENT_SOURCE_DIR}/../third-party/SFML/cmake/Modules")
# SFML
#set(SFML_STATIC_LIBRARIES TRUE) # Can't compile static yet
set(SFML_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../intermediate/SFML/")
set(SFML_ROOT "${CMAKE_CURRENT_SOURCE_DIR}/../third-party/SFML/")
#set(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "${CMAKE_CURRENT_SOURCE_DIR}/../third-party/SFML/cmake/Modules")
#set(SFML_ROOT ${SFML_ROOT} "${CMAKE_CURRENT_SOURCE_DIR}/../third-party/SFML/cmake/Modules")
#message(STATUS "CMAKE_LIBRARY_PATH: ${CMAKE_LIBRARY_PATH}")
find_package(SFML 2.5 COMPONENTS graphics audio network REQUIRED)
# Imgui
find_package(imgui)
include_directories(${IMGUI_INCLUDE_DIRS})
find_package(imgui-sfml)
include_directories(${IMGUI_SFML_INCLUDE_DIRS})
add_executable(my_proj ../main.cpp)
target_link_libraries(my_proj
sfml-graphics
sfml-audio
sfml-network
imgui
imgui-sfml
)
add_dependencies(my_proj
imgui
imgui-sfml
)
If I compile SFML as a shared library, I can get pretty close - but my_proj and imgui-sfml are trying to use .lib files instead of .dll files, so I get linker errors.
Contents of Findimgui-sfml.cmake:
cmake_minimum_required(VERSION 3.1)
project(imgui-sfml)
file(GLOB_RECURSE IMGUI_SFML_SRC
"${CMAKE_CURRENT_SOURCE_DIR}/../third-party/imgui-sfml/*.cpp"
)
find_package(SFML 2.5 COMPONENTS graphics REQUIRED)
set(IMGUI_SFML_INCLUDE_DIRS "${CMAKE_CURRENT_SOURCE_DIR}/../third-party/imgui-sfml/")
add_library(imgui-sfml STATIC
${IMGUI_SFML_SRC}
)
target_link_libraries(imgui-sfml
sfml-graphics
)
If I try to compile SFML statically, I get errors about missing packages:
-- Selecting Windows SDK version 10.0.17134.0 to target Windows 10.0.16299.
CMake Error at D:/code/my_proj/intermediate/SFML/SFMLConfig.cmake:139 (message):
SFML found but some of its dependencies are missing ( FreeType OpenAL Ogg
Vorbis VorbisFile VorbisEnc FLAC)
Call Stack (most recent call first):
CMakeLists.txt:28 (find_package)
CMake Error at CMakeLists.txt:28 (find_package):
Found package configuration file:
D:/code/my_proj/cmake/../intermediate/SFML/SFMLConfig.cmake
but it set SFML_FOUND to FALSE so package "SFML" is considered to be NOT
FOUND.
-- Configuring incomplete, errors occurred!
I would appreciate any help/suggestions with this.
Thanks for your time, and please let me know if more information is required.
Thanks!
