When running g-ir-compiler, augment LD_LIBRARY_PATH with the current
directory, rather than overwriting it entirely.
svn path=/trunk/; revision=27
# The dependency on libgnome-shell.la here is because g-ir-compiler opens it
# (not the fake library, since we've already done the rewriting)
Shell-0.1.typelib: libgnome-shell.la Shell-0.1.gir
- LD_LIBRARY_PATH=. g-ir-compiler Shell-0.1.gir -o $@
+ LD_LIBRARY_PATH=$${LD_LIBRARY_PATH:+$$LD_LIBRARY_PATH:}. g-ir-compiler Shell-0.1.gir -o $@
