Not relevant

I use homebrew, if that is relevant.

[designermonkey]

export CPPFLAGS="$CPPFLAGS -I$(brew --prefix pcre2)/include -L$(brew --prefix pcre2)/lib"

Seems to have fixed it.

On a side note, a similar problem applies with openssl, fixed with the following:

export LDFLAGS="$LDFLAGS -I$(brew --prefix openssl)/include -L$(brew --prefix openssl)/lib"
export CPPFLAGS="$CPPFLAGS -I$(brew --prefix openssl)/include -L$(brew --prefix openssl)/lib"

[designermonkey]

Now there is a problem with mkdir at the end of the build :( I need sudo for it to work, but sudo means the build fails with the same issues above.

[david-d-h]

I've had this before too, this fixed the problem for me. It's annoying to have to use a workaround, but it works. https://freek.dev/2151-fixing-the-dreaded-pcre2h-file-not-found-error-when-installing-imagick

As for the openssl error, it might be the same fix. Haven't tried.
