将SOIL2库包含在CMake项目中

Question

我正在尝试将SOIL2包含在我的C++ OpenGL项目中。

到目前为止我

• 从https://github.com/SpartanJ/SOIL2下载库
• 通过运行premake4和make构建它。
• 将src/SOIL2 2/目录复制到/usr/local/include
• 尝试向/usr/local/lib添加libsoil2 2-调试器。
• 以下是包含CMake库的各种方法的示例

平台是MacOS (Catalina)，我对CMake还不熟悉，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是我包含土壤的文件，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;
};

这些都是我在运行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

任何帮助都很感激！

最后使用下面的CMakeLists文件构建项目。谢谢你的回复！

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}
)

Answer 2

看来没能找到libsoil2 2-调试器。尝试将/usr/local/lib添加到路径中：

list(APPEND CMAKE_PREFIX_PATH "/usr/local/lib")

在CMakeList.txt文件顶部的某个地方
