[Rspamd-Users] rspamd src-build fails to locate/use pcre2 install ?

[PGNet Dev]

building on linux, i've got pcre & pcre2 installed

	/usr/local/bin/pcre-config --version
		8.44

	/usr/local/bin/pcre2-config --version
		10.35-RC1

pkg-config lists,

	pkg-config --list-all | grep pcre
		libpcreposix              libpcreposix - PCREPosix - Posix compatible interface to libpcre
		libpcre2-8                libpcre2-8 - PCRE2 - Perl compatible regular expressions C library (2nd API) with 8 bit character support
		libpcre                   libpcre - PCRE - Perl compatible regular expressions C library with 8 bit character support
		libpcre16                 libpcre16 - PCRE - Perl compatible regular expressions C library with 16 bit character support
		libpcrecpp                libpcrecpp - PCRECPP - C++ wrapper for PCRE
		libpcre2-posix            libpcre2-posix - Posix compatible interface to libpcre2-8

the pcre2-relevant pkg-configs are

	pkg-config --libs --cflags libpcre2-posix
		-I/usr/local/include -L/usr/local/lib64 -lpcre2-posix
	pkg-config --libs --cflags libpcre2-8
		-I/usr/local/include -L/usr/local/lib64 -lpcre2-8

config'ing rspamd with,

	cmake -DENABLE_PCRE2=1 ...

*ignores* existence of pcre2 install,

	grep -i pcre CMakeCache.txt

what's the correct, necessary config to enable/find the installed pcre*2*?
