Compile caffe while another caffe exists already

1. Problem

[dashuage caffe-fast-rcnn]$ makeCXX/LD -o .build_release/examples/cifar10/convert_cifar_data.bin/usr/bin/ld: warning: libhdf5_hl.so.100, needed by /usr/lib/libcaffe.so, may conflict with libhdf5_hl.so.10/usr/bin/ld: warning: libhdf5.so.100, needed by /usr/lib/libcaffe.so, may conflict with libhdf5.so.10/usr/bin/ld: .build_release/examples/cifar10/convert_cifar_data.o: undefined reference to symbol '_ZdlPvm'/usr/lib/libtcmalloc.so.4: error adding symbols: DSO missing from command linecollect2: error: ld returned 1 exit statusmake: *** [Makefile:613: .build_release/examples/cifar10/convert_cifar_data.bin] Error 1

2. Analysis

When make, it does three things:
- make lib
- make tools
- make examples
This error occured when make the latter two objects.

Since there is another caffe installed already, we don’t really need to rebuild tools and examples. Use ln to link.

3. Solution

1. Edit Makefile
   
#all: lib examples tools
all: lib

2. make all
3. set link
