-# This is necessary when building on Windows in VS (ABI conflicts between MT and MTd).

-# Usage: find_cpp_library(<RETURNVAR> <LIBNAME> [NOCACHE])
-# Arguments:
-#   VAR        –   Output variable
-#   LIB        -   the Library name
-# Example: find_cpp_library(PROTOBUF_LIBRARIES protobuf)

-# Search for multiple libraries with multiple possible names
-#
-# This is be useful, when a module requires multiple libs or
-# when a lib can have multiple names.
-#
-# Wrapper around find_cpp_library, so libs with debug and
-# release versions are supported, which in turn is a wrapper
-# around find library, so you can omit /^lib/ and the usual
-# suffixes (.dll/.so/.o/.obj/.a)
-#
-# USAGE: find_libs(<OUTVAR> lib1_names...
-#     [LIB libN_names... ]... NOCACHE)
-#
-# EXAMPLE:
-#     You are working on module `cuteness` module cuteness;
-#     cuteness depends on two libraries: libkittens.so and
-#     libdog.a; libdog.a might however also be called libpuppy.so.
-#     You could use the following command:
-#
-#     find_libs(CUTENESS_LIBS kittens LIB dog puppy)
