So from the silence, either I described my issue badly, or there isn't a
way?

>From the script at the end, when generating 'unix makefiles' with a mingw
environment, or MingW makefiles, these are the gcc commands....

(compile .obj)
c:/tools/unix/mingw.mangled/bin/gcc.exe  -Dtest2_EXPORTS  -o
CMakeFiles/test2.dir/test2.c.obj   -c M:/tmp/cmake_crash/test4/test2.c
(link .dll)
c:/tools/unix/mingw.mangled/bin/gcc.exe     -shared -o libtest2.dll
-Wl,--out-implib,libtest2.dll.a
-Wl,--major-image-version,0,--minor-image-version,0
-Wl,@CMakeFiles/test2.dir/objects1.rsp -lkernel32 -luser32 -lgdi32
-lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32
(compile .obj)
c:/tools/unix/mingw.mangled/bin/gcc.exe    -o
CMakeFiles/test1.dir/test1.c.obj   -c M:/tmp/cmake_crash/test4/test1.c
(link .exe)
c:/tools/unix/mingw.mangled/bin/gcc.exe
 -Wl,@CMakeFiles/test1.dir/objects1.rsp  -o test1.exe
-Wl,--out-implib,libtest1.dll.a
-Wl,--major-image-version,0,--minor-image-version,0  libtest2.dll.a
-lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid
-lcomdlg32 -ladvapi32

In the link .exe step, it references the full name (and full path) of the
libtest2.dll.a ... if this were a more complex case where a library is
built in the root, the path could be like ../../../../liblib.dll.a.  Now,
as a windows target this doesn't matter so much, but when using a toolchain
file to target android, the full path to the .so gets embedded.....

 libtest2.so

see... libtest2.so

.....
So, since I REALLY need a solution for this; I guess, what I can do is
stretch out the projects into multiple cmake passes, and treat it more like
an installed library.
