Suppressing warnings generated by libPNG

Hi team,
I am developing an application that uses libpng for reading/writing PNG
files. I am upgrading from using version 1.2.39 to 1.6.35 of the library.

After this upgrade, I noticed that reading many files in my repository
resulted in the warning:
iCCP: known incorrect sRGB profile

I believe this was introduced in 1.6.x.

I have fixed all the PNG files that I ship with my application. However, as
my users have PNG files that might suddenly result in a warning when read,
is there a way I can suppress this warning when building the library?

The current workaround I have is to inspect the message in my
WarningHandler for this specific string and filter it out which does not
appear to be a robust solution.

Regards,
Dinesh
