【问题描述】：
我收到错误消息： :-1: Fehler: 错误: gegl-0.4: 找不到链接器输入文件: 没有这样的文件或目录 :-1: Fehler: error: babl-01: linker input file not found: No such file or directory
因此链接器无法找到库或由于未知原因无法链接它们。
我试过了：
cmake_minimum_required(VERSION 3.5)
project(perspective_lines LANGUAGES C)
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -lm gegl-0.4 babl-01 ")
#export (PKG_CONFIG_PATH="${GIMP_PREFIX}/share/pkgconfig:${GIMP_PREFIX}/lib64/pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"")
#add_compile_options( -L/usr/lib64/libm.so -lm -std=gnu11 -v)

add_executable(perspective_lines perspective_lines.c)

target_link_libraries(perspective_lines "/usr/lib64/libgegl-04.so")
#target_link_libraries(perspective_lines gegl)
install(TARGETS perspective_lines DESTINATION ~/.config/GIMP/2.10/plug-ins/)
这也不起作用： 设置(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -lm gegl-0.4 -L /usr/lib64/libgegl-04.so")
我的错误在哪里？

This doesn't work also所以不用它？Where is my mistake ?你的错误是将gegl-0.4传递给编译器，不要这样做。 ||天哪，这么多 GTK2_*_STUFF。你不能只使用GTK2_INCLUDE_DIRS和GTK2_LIBRARIES吗？ -
请澄清您的具体问题或提供更多详细信息以准确突出您的需求。正如目前所写的那样，很难准确地说出你在问什么。
