undefined reference to symbol 'XConvertSelection'

问题中提到的错误"undefined reference to symbol 'XConvertSelection'"是由于缺少对X11库的链接导致的。根据引用\[1\]和引用\[2\]的建议，在CMakeLists.txt文件的target_link_libraries中添加"-lX11"可以解决这个问题。如果问题仍然存在，可以尝试在CMakeLists.txt中添加"find_package(X11 REQUIRED)"，并在target_link_libraries中添加"${X11_Xrandr_LIB}"、"${X11_Xi_LIB}"、"${X11_Xrender_LIB}"、"${X11_Xdamage_LIB}"、"${X11_Xext_LIB}"、"${X11_X11_LIB}"、"${X11_Xinerama_LIB}"、"${X11_Xcursor_LIB}"来链接X11库。\[2\]
