Link cv_bridge with opencv 3.4.15

[Rui Mao]

I use the noetic branch of vision_opencv. Because I want to use opencv 3.4.15, I modify the CMakeLists.txt like following:

Then I came up with the error when I complile it

  * The path was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and references files it does not
  provide.

I have no idea what should I do
I worked in :

• Ubuntu 20.04 on Raspberry Pi
• ros noetic and I have removed the original cv_bridge

According to the following VowpalWabbit/vowpal_wabbit#3003, which was referenced here, you need to create a symlink for /include -> /usr/include. To do so run the following command in the Terminal:
sudo ln -s /usr/include /include

@Snow-know-nothing Did you want to keep this open? Did the work around suggested work?
