对‘TIFFReadDirectory@LIBTIFF_4.0’未定义的引用

在执行makefile文件时，出现如下错误：

查找libopencv_imgcodecs.so的依赖：
ldd /home/zwl/software/opencv4.2/lib/libopencv_imgcodecs.so
linux-vdso.so.1 (0x00007fff9c1f0000)
libopencv_imgproc.so.4.2 => /home/zwl/software/opencv4.2/lib/libopencv_imgproc.so.4.2 (0x00007f1a4e0cc000)

libopencv_core.so.4.2 => /home/zwl/software/opencv4.2/lib/libopencv_core.so.4.2 (0x00007f1a4d34f000)

libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f1a4cda9000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f1a4ca0b000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f1a4c7f3000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f1a4c5d4000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f1a4c1e3000)
liblzma.so.5 => /lib/x86_64-linux-gnu/liblzma.so.5 (0x00007f1a4bfbd000)
libjbig.so.0 => /usr/lib/x86_64-linux-gnu/libjbig.so.0 (0x00007f1a4bdaf000)

/lib64/ld-linux-x86-64.so.2 (0x00007f1a4ee11000)
从libtiff.so.5 => /usr/lib/x86_64-linux-gnu/libtiff.so.5 (0x00007f1a4d9ba000)可看出：libopencv_imgcodecs.so依赖libtiff.so.5，且libtiff.so.5在目录 /usr/lib/x86_64-linux-gnu/下。
也就是说libopencv_imgcodecs.so库会去目录 /usr/lib/x86_64-linux-gnu/下查找依赖libtiff.so.5
然后我发现我用-L指定的目录$(python_path)/lib下也有库libtiff，这就是问题所在：
libopencv_imgcodecs.so首先会去目录$(python_path)/lib下查找库libtiff，然后就找到了libtiff，但是由于版本不一致，就会出现上面的错误。
解决方法：让libopencv_imgcodecs.so先去查找目录 /usr/lib/x86_64-linux-gnu/，而不是目录$(python_path)/lib，即在-L $(python_path)/lib前加上-L /usr/lib/x86_64-linux-gnu/，即：
-L /usr/lib/x86_64-linux-gnu/ -L $(python_path)/lib
出现以上错误，是由于版本不一致导致的。
