I'm working on a renderer for Vulkan API. I have big trouble setting up the project correctly using CMake and conan package manager. Let's take a look at my conanfile.py for dependency setup:
from conans import ConanFile, CMake
class InexorConan(ConanFile):
settings = (
"os",
"compiler",
"build_type",
"arch"
)
requires = (
"benchmark/1.5.0",
"glm/0.9.9.7",
"gtest/1.10.0",
"spdlog/1.5.0",
"glfw/3.3.2@bincrafters/stable",
"toml11/3.1.0",
"imgui/1.75",
"assimp/5.0.1",
"enet/1.3.14 "
)
generators = "cmake"
default_options = {
}
def imports(self):
# Copies all dll files from packages bin folder to my "bin" folder (win)
self.copy("*.dll", dst="bin", src="bin")
# Copies all dylib files from packages lib folder to my "lib" folder (macosx)
self.copy("*.dylib*", dst="lib", src="lib") # From lib to lib
# Copies all so files from packages lib folder to my "lib" folder (linux)
self.copy("*.so*", dst="lib", src="lib") # From lib to lib
def build(self):
cmake = CMake(self)
cmake.configure()
cmake.build()
All the conan setup is working correctly, as can be seen by CMake output:
Sadly, there is no conan setup for Vulkan API. So I am using some code of Sascha Willem's github repository. My CMake file looks like this:
cmake_minimum_required(VERSION 3.4)
project(inexor-vulkan-renderer)
file(GLOB_RECURSE source_files
"src/*.hpp"
"src/*.cpp"
)
# Use the folder structure in source code directory as project structure in Visual Studio.
function(assign_source_group)
foreach(source_files IN ITEMS ${ARGN})
if (IS_ABSOLUTE "${source_files}")
file(RELATIVE_PATH _source_rel "${CMAKE_CURRENT_SOURCE_DIR}" "${source_files}")
else()
set(_source_rel "${source_files}")
endif()
get_filename_component(_source_path "${_source_rel}" PATH)
string(REPLACE "/" "\\" _source_path_msvc "${_source_path}")
source_group("${_source_path_msvc}" FILES "${source_files}")
endforeach()
endfunction(assign_source_group)
# Use CMake to find Vulkan SDK.
if (NOT CMAKE_VERSION VERSION_LESS 3.7.0)
message(STATUS "Using module to find Vulkan")
find_package(Vulkan)
endif()
# Dependency setup via conan.
# Download conan executer in case it does not exists.
if(NOT EXISTS "${CMAKE_CURRENT_BINARY_DIR}/conan.cmake")
message(STATUS "Downloading conan.cmake from https://github.com/conan-io/cmake-conan")
file(DOWNLOAD "https://raw.githubusercontent.com/conan-io/cmake-conan/v0.14/conan.cmake"
"${CMAKE_CURRENT_BINARY_DIR}/conan.cmake")
endif()
# Execute conan build instructions.
include(${CMAKE_CURRENT_BINARY_DIR}/conan.cmake)
conan_cmake_run(CONANFILE conanfile.py
BASIC_SETUP
BUILD outdated
PROFILE default
PROFILE_AUTO build_type
KEEP_RPATHS
)
# Use the folder structure in source code directory as project structure in Visual Studio.
assign_source_group(${source_files})
add_executable(inexor-vulkan-renderer src/main.cpp ${source_files})
target_link_libraries(inexor-vulkan-renderer PUBLIC ${Vulkan_LIBS} ${CONAN_LIBS})
# Use C++17!
target_compile_features(inexor-vulkan-renderer PRIVATE cxx_std_17)
IF(WIN32)
target_compile_definitions(inexor-vulkan-renderer PRIVATE VK_USE_PLATFORM_WIN32_KHR)
ENDIF()
target_include_directories(inexor-vulkan-renderer PRIVATE Vulkan::Vulkan)
target_link_libraries(inexor-vulkan-renderer Vulkan::Vulkan)
When I generate a Visual Studio project file with this setup, I have to add glfw3.lib, spdlogd.lib and fmtd.lib to the project manually. Other repositories like the official Vulkan samples take a more traditional approachand just paste the libs directly into the repo folders. I don't want to do this since I want conan to work for me. I've been trying to fix this problem for 6 months now.
Why does CMake not link the needed libraries although conan can find them?
Thanks you.
