I echoed these in "pre-everything" section. Now I set "LDFLAGS+=   
-L${LOCALBASE}/lib", but it doesn't help much. My Makefile is structured
smth like that:

PORTNAME=...
...
USE_CMAKE=      yes
...
LDFLAGS+=       -L${LOCALBASE}/lib
CMAKE_ARGS+=    -DCMAKE_REQUIRED_INCLUDES="${LOCALBASE}/include"
...
OPTIONS=...
...
.include <bsd.port.pre.mk>
...
pre-everything::
        @${ECHO_MSG} "${CXXFLAGS}"
        @${ECHO_MSG} "${LDFLAGS}"
...
post-install:
...
.include <bsd.port.post.mk>
