[Uml-devel] Q: using ccache?

I yesterday tried to use ccache to fasten compilation of umbrello. This failed 
because the definition of CXX='ccache g++' lead to libtool thinking that g++ 
is one file to link with while linking the code generators library.

Here is the output of linking at this stage:

ccache g++ -shared -nostdlib /usr/lib/crti.o 
/usr/lib/gcc-lib/i486-suse-linux/2.95.3/crtbeginS.o  .libs/javawriter.o 
.libs/factory.o .libs/cppwriter.o .libs/phpwriter.o  
- -L/usr/lib/gcc-lib/i486-suse-linux/2.95.3 -L/usr/i486-suse-linux/lib -lstdc++ 
- -lm -lc -lgcc /usr/lib/gcc-lib/i486-suse-linux/2.95.3/crtendS.o 
/usr/lib/crtn.o   g++ -Wnon-virtual-dtor -Wno-long-long -Wbad-function-cast 
- -Wundef -Wall -pedantic -W -Wpointer-arith -Wmissing-prototypes 
- -Wwrite-strings -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align 
- -Wconversion -fno-builtin -g -O2 -fno-exceptions -fno-check-new 
- -Iuml/classparser -Iuml/dialogs -Iuml/clipboard -Wl,-soname 
- -Wl,libcodegenerator.so.0 -o .libs/libcodegenerator.so.0.0.0

But maybe you have another way to keep the CVS sources compilation up to date. 
Currently I copy the whole CVS source tree to another place and do a complete 
recompilation. That is normally to much work than what would be necessary. In 
most cases it would suffice to copy the changed source files of the CVS tree 
to the old copy and then start compilation. Is there a simple way to have CVS 
tree and compilation tree in sync this way?
