C++

Hi, i’m trying to install Opencv on my Ubuntu.
But when i used “Cmake”, it shows these Warning.
What can i do now?
Cannot generate a safe runtime search path for target opencv_imgcodecs
because files in some directories may conflict with libraries in implicit
directories:

runtime library [libjpeg.so.8] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /home/linuxbrew/.linuxbrew/lib
runtime library [libpng16.so.16] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /home/linuxbrew/.linuxbrew/lib
runtime library [libz.so.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /home/linuxbrew/.linuxbrew/lib
runtime library [libtiff.so.5] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /home/linuxbrew/.linuxbrew/lib

Some of these libraries may not be found correctly.

how, exactly ?

is that, when building opencv libs, or when trying to build your own program ?

what is that ? do you absolutely need it ?

try to use the 3rd party code, that comes with opencv, so the imgcodecs module will link static libs, and it wont try to use your (shadowed) system libs, by adding

-DBUILD_PNG -DBUILD_ZLIB -DBUILD_TIFF

to the cmake cmdline
