使用Conan包管理器时sol2查找失败，Lua无法正常链接

构建命令 #

conan install . --install-folder build --build=missing
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=build/conan_toolchain.cmake -S . -B build -GNinja
cmake --build build

报错信息 #

CMake Error at CMakeLists.txt:16 (find_package):
  By not providing "Findsol2.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "sol2", but
  CMake did not find one.

  Could not find a package configuration file provided by "sol2" with any of
  the following names:

    sol2Config.cmake
    sol2-config.cmake

  Add the installation prefix of "sol2" to CMAKE_PREFIX_PATH or set
  "sol2_DIR" to a directory containing one of the above files.  If "sol2"
  provides a separate development package or SDK, be sure it has been
  installed.

注：SDL2可正常识别，仅sol2出现上述报错。

解决方案 #

修改后的CMakeLists.txt #

cmake_minimum_required(VERSION 3.20)
project(game)

set(SOURCES 
    ${CMAKE_CURRENT_SOURCE_DIR}/src/main.cpp
)


# Conan Requirements
include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
conan_basic_setup()

add_executable(game ${SOURCES})

find_package(SDL2 REQUIRED)
find_package(sol2 REQUIRED)

target_compile_options( game PRIVATE 
    $<$<CONFIG:Debug>:
        -fsanitize=address,leak
    >
)

target_link_options( game PRIVATE 
    $<$<CONFIG:Debug>:
        -fsanitize=address,leak
    >
)

target_compile_features(game
    PRIVATE
        cxx_std_20
)

target_link_libraries(game PRIVATE 
    SDL2::SDL2
    sol2::sol2
)

修改点：将target_link_libraries中的sol2::sol改为sol2::sol2，匹配sol2包导出的正确目标名称。

修改后的conanfile.txt #

[requires]
sol2/3.3.0
sdl/2.0.20

[generators]
cmake
cmake_find_package
CMakeDeps
CMakeToolchain

修改点：添加sol2/3.3.0到依赖列表，移除原有的lua/5.4.4（sol2会自动关联对应版本的lua，无需单独声明）。

修改后的构建脚本 #

#!/usr/bin/sh

conan install . --install-folder build --build=missing
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=build/conan_toolchain.cmake -S . -B build -GNinja
