pkg-config has a --static option to list libraries required for a static
build.

$ pkg-config --libs libtiff-4
-ltiff

$ pkg-config --static --libs libtiff-4
-ltiff -llzma -ljbig -ljpeg -lz -lm

You can try grepping the CMakeCache.txt. eg

$ grep -i cairo CMakeCache.txt  | grep -i static

shows a variable with static link flags

_pc_cairo_STATIC_LDFLAGS:INTERNAL=-lcairo;-lz;-lgobject-2.0;-lffi;-lglib-2.0;-pthread;-lpcre;-pthread;-lpixman-1;-lfontconfig;-lexpat;-lfreetype;-lexpat;-lfreetype;-lz;-lpng16;-lm;-lz;-lm;-lpng16;-lm;-lz;-lm;-lxcb-shm;-lxcb-render;-lXrender;-lXext;-lX11;-lpthread;-lxcb;-lXau;-lXdmcp

but

$ grep -i tiff CMakeCache.txt  | grep -i static

does not show any static link flags. For some reason cmake is not
finding the libtiff static link flags.
