## lib_env(CXX) The compiler used to run testcases.

## lib_env(CXXFLAGS) Special flags passed to the compiler.
|
|
## lib_env(INCLUDES) Includes options to pass to the compiler.
|
|
## lib_env(LDFLAGS) Additional library flags.
|
|
## lib_env(LIBTOOL) Path to the `libtool' script.
|
|
## lib_env(SRC_DIR) Where V3 master source lives.
|
|
## lib_env(BUILD_DIR) Where V3 is built.
|
|
## lib_env(static) Flags to pass to the linker to build a
|
|
## statically linked executable.
|
|
## lib_env(shared) Flags to pass to the linker to build a
|
|
## dynamically linked executable.
