Magick++ - 对符号"ImagesToBlob"的未定义引用

Question

我是c++的新手，我最近在WSL2上安装了magick++，以便在cmake的c++项目中使用它，但是当我试图使用它时，它显示了一个错误。

我已经尝试了很多事情。

如何安装magic ++

sudo apt-get install -y libmagick++-dev

My cmake file

...
# Linking libraries
find_package(PkgConfig REQUIRED)
pkg_search_module(dpp REQUIRED dpp)
target_link_libraries(${PROJECT_NAME} dpp)
add_definitions(-DMAGICKCORE_QUANTUM_DEPTH=16)
add_definitions(-DMAGICKCORE_HDRI_ENABLE=1)
find_package(ImageMagick COMPONENTS Magick++)
include_directories(${ImageMagick_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${ImageMagick_LIBRARIES})
# Set C++ version
set_target_properties(${PROJECT_NAME} PROPERTIES
CXX_STANDARD 20
CXX_STANDARD_REQUIRED ON
)

我的代码

int width = 300;
int height = 200;
vector<Image> frames;
for (int i=0;i<20;i++) {
Geometry newSize(width, height);
Image img(newSize, Color("black"));
img.draw({
DrawableFont("Helvetica"),
DrawableText(width / 3, height / 2, to_string(i)),
DrawableStrokeColor(Color("white")),
DrawableFillColor(Color("blue"))
});
img.animationDelay(1000 / 20);
img.magick("GIF");
frames.push_back(img);
}
Blob blob;
writeImages(frames.begin(), frames.end(), &blob);
event.reply(dpp::message().add_file("test.gif", blob.base64()));

误差

我需要安装libmagickcore-dev

sudo apt install -y libmagickcore-dev

将MagickCore添加到c组件中

find_package(ImageMagick COMPONENTS Magick++ MagickCore)
