- This variable holds a space separated list of libraries that
- should be linked into the program. These libraries must either
- be LLVM libraries or libraries that come from your lib

- For example, to link libsample.a, you would set USEDLIBS to
- sample.

LLVMLIBS
+
+ This variable holds a space separated list of libraries that should
+ be linked into the program. These libraries must be LLVM libraries.
+ The libraries must be specified without their "lib" prefix. For
+ example, to link with a driver that performs an IR transformation
+ you might set LLVMLIBS to this minimal set of libraries
+ LLVMSupport.a LLVMCore.a LLVMBitReader.a LLVMAsmParser.a LLVMAnalysis.a LLVMTransformUtils.a LLVMScalarOpts.a LLVMTarget.a.
+
+ Note that this works only for statically linked libraries. LLVM is
+ split into a large number of static libraries, and the list of libraries you
+ require may be much longer than the list above. To see a full list
+ of libraries use:
+ llvm-config --libs all.
+ Using LINK_COMPONENTS as described below, obviates the need to set LLVMLIBS.

LINK_COMPONENTS
