# @synopsis:
#
# The 'cc-shared' module provides support for shared libraries and shared objects.
# It defines the following variables:
#
## SH_CFLAGS Flags to use compiling sources destined for a shared library
## SH_LDFLAGS Flags to use linking a shared library
## SHOBJ_CFLAGS Flags to use compiling sources destined for a shared object
## SHOBJ_LDFLAGS Flags to use linking a shared object, undefined symbols allowed
## SHOBJ_LDFLAGS_R - as above, but all symbols must be resolved
## SH_LINKFLAGS Flags to use linking an executable which will load shared objects
## LD_LIBRARY_PATH Environment variable which specifies path to shared libraries
