I do note the 'trying hard', although I see no attempts to find in
*/lib64, or use pkg-config or pcre-config.

On my system, src is in 


pcre's configured as shared-only, with pcre-jit enabled,

	./configure --enable-shared --disable-static --enable-jit
	--enable-pcregrep-jit ...

and build's installed in

	/usr/local/bin/pcre-config --version
	pcre-config --libs --cflags
		-L/usr/local/lib64 -lpcre
	pkg-config libpcre --libs --cflags
		-I/usr/local/include  -L/usr/local/lib64 -lpcre

That said, if I want nginx to enable pcre use, use pcre-jit, and use
specifically that locally-installed pcre(jit) instance, what's the right
nginx config?


	--with-pcre=/usr/local/src/pcre --with-pcre-jit

does not appear to be the correct choice.
