Space in path causes compilation error

[ghost]

$ ./configure && make

...
./libtool --tag=CC --quiet --mode=compile clang -Wall -I/usr/include/libxml2 -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2  -O3 -DNDEBUG -fvisibility=hidden -D_THREAD_SAFE -pthread -DNC_WORKINGDIR_PATH=\"//var/lib/libnetconf/\" -DNC_SESSIONFILE_PATH=\"//var/lib/libnetconf/\" -DNCNTF_STREAMS_PATH=\"//var/lib/libnetconf//streams/\" -DSETBIT=0  -DRCSID=\""built from git 49c791ceb2009b5897b0"\" -I/test 123/libnetconf/src  -fPIC -c src/callbacks.c -o .obj/src/callbacks.lo
clang: error: no such file or directory: '123/libnetconf/src'

Seeing the above error. My directory path where I downloaded libnetconf is below:

$ pwd
/test 123/libnetconf

Any idea how to fix this?

Thanks
