[CMake] idea for shorter linker commands

[Alexander Neundorf]

Hi, 
 
recently I read that you are trying to reduce the length of the required 
linker commands. 
How about executing the linker command from the directory, where the 
object files are located, instead of executing it from the top directory, 
i.e.  
 
cd CMakeFiles/test.dir && c++ -fPIC "main.o" "foo.o" -o ../../test 
-rdynamic 
 
instead of: 
 
c++ -fPIC "CMakeFiles/test.dir/main.o" "CMakeFiles/test.dir/foo.o" -o 
test -rdynamic 
 
This would work even better if the object files would again all be 
located in one directory, and not distributed in subdirectories arranged 
parallel to the subdirectories of the source files ? 
 
Bye 
Alex
