c++ - 在 CMake 项目中包含 SOIL2 库

Question

我正在尝试将 SOIL2 包含在我的 C++ OpenGL 项目中。

到目前为止我已经

• 从 https://github.com/SpartanJ/SOIL2 下载该库
• 通过运行 premake 4 和 make 来构建它。
• 将 src/SOIL2/目录复制到/usr/local/include
• 尝试将 libsoil2-debug.a 添加到/usr/local/lib
• 遵循使用 CMake 包含库的各种方法示例

平台是 MacOS (Catalina) 我对 CMake 还很陌生，所以我很确定这就是我的问题所在。

目前，我的 CMakeLists 文件如下所示:

cmake_minimum_required(VERSION 3.8)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_C_STANDARD 99)
set(This ComputerGraphicsProgramming)
project(${This} CXX C)

file(GLOB_RECURSE SOURCES src/*.cpp)
file(GLOB_RECURSE SOIL2_SOURCES /usr/local/include/SOIL2/*.c)
add_executable(${This} ${SOURCES} ${HEADERS})

include_directories(
  include
  lib
  /usr/local/include
)
link_directories(
  /usr/local/include
  /usr/local/include/SOIL2
)

find_package(OpenGL REQUIRED)
find_package(glfw3 REQUIRED)
find_package(glew REQUIRED)
find_package(glm REQUIRED)
find_library(soil2-debug REQUIRED)

target_link_libraries(${This}
  GLEW::GLEW
  ${OPENGL_LIBRARIES} glfw
  soil2-debug
)

Texture.hpp，我在其中包含 SOIL 的文件，如下所示:

#include <GL/glew.h>
#include <SOIL2/SOIL2.h>
#include <string>

class Texture
{
  public:
    Texture(std::string filename);
    ~Texture();

  private:
    unsigned int m_ID;
};

这些是我运行 make 时的错误:

$ make
[  9%] Linking CXX executable ComputerGraphicsProgramming
ld: library not found for -lsoil2-debug
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [ComputerGraphicsProgramming] Error 1
make[1]: *** [CMakeFiles/ComputerGraphicsProgramming.dir/all] Error 2
make: *** [all] Error 2

感谢任何帮助!

终于使用以下 CMakeLists 文件构建了项目。谢谢各位的回复!

cmake_minimum_required(VERSION 3.8)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_C_STANDARD 99)
set(This ComputerGraphicsProgramming)

project(${This} CXX C)

file(GLOB_RECURSE SOURCES src/*.cpp)
add_executable(${This} ${SOURCES} ${HEADERS})

include_directories(
  include
  /usr/local/include
)

find_package(OpenGL REQUIRED)
find_package(glfw3 REQUIRED)
find_package(glew REQUIRED)
find_package(glm REQUIRED)
find_library(SOIL2 soil2-debug)

target_link_libraries(${This}
  GLEW::GLEW
  ${OPENGL_LIBRARIES} glfw
  ${SOIL2}
)
