LLVM. Typically called from 'configure' scripts. Examples:

--includedir Directory containing LLVM headers.
|
||||
--libdir Directory containing LLVM libraries.
|
||||
--cppflags C preprocessor flags for files that include LLVM headers.
|
||||
--cflags C compiler flags for files that include LLVM headers.
|
||||
--cxxflags C++ compiler flags for files that include LLVM headers.
|
||||
--ldflags Print Linker flags.
|
||||
--libs Libraries needed to link against LLVM components.
|
||||
--libnames Bare library names for in-tree builds.
|
||||
--libfiles Fully qualified library filenames for makefile depends.
|
||||
--components List of all possible components.
|
||||
--targets-built List of all targets currently built.
|
||||
--host-target Target triple used to configure LLVM.
|
||||
--build-mode Print build mode of LLVM tree (e.g. Debug or Release).
|
||||
Typical components:
|
||||
all All LLVM libraries (default).
