Don't do that :-).

In general, using link_directories is discouraged. It is preferred to 
give only targets or full paths to target_link_libraries(). (Use 
find_library as needed to resolve 'pretty' names to full names with 
platform-specific prefixes and suffixes.)

So to have B link to /path/to/Foo/libA, and C link to /path/to/Bar/libA, 
just do:

target_link_libraries(B /path/to/Foo/libA)
target_link_libraries(C /path/to/Bar/libA)
