编译的时候 -lfiniteVolume已经包含了，为什么提示fvc::grad() not declared?

make/option文件内容

EXE_INC = \
    -I$(LIB_SRC)/transportModels/twoPhaseMixture/lnInclude \
    -I$(LIB_SRC)/transportModels \
    -I$(LIB_SRC)/transportModels/incompressible/lnInclude \
    -I$(LIB_SRC)/finiteVolume/lnInclude

LIB_LIBS = \
    -ltwoPhaseMixture \
    -ltwoPhaseProperties \
    -lincompressibleTransportModels \
    -lfiniteVolume
