# Provides support to depend on LLVM
#
# USES=llvm supports two kinds of arguments:
#
# * mode
# <none>: defaults to build
# build: add a BUILD_DEPENDS on chosen llvm-port
# run: add a RUN_DEPENDS on chosen llvm-port
# lib: add a LIB_DEPENDS on chosen llvm-port
#
# * version
# <none>: defaults to ${LLVM_DEFAULT}
# number: use explicitly the specified version
# min=number: use specified min if ${LLVM_DEFAULT} is lower
# max=number: use specified max if ${LLVM_DEFAULT} is higher
#
# * environment
# export: do export CC, CXX,... variables [default]
# noexport: do not export CC,CXX,... variables
#
# An example usage might be:
# USES= llvm
# or
# USES= llvm:13,build
# or
# USES= llvm:min=14,lib
#
# The following variables are exposed to be used in the ports tree at the moment:
# * LLVM_VERSION version chosen from the arguments to llvm.mk
# * LLVM_PORT chosen llvm port
# * LLVM_CONFIG llvm-config of the chosen port
# * LLVM_LIBLLVM libLLVM.so of the chosen port
# * LLVM_PREFIX installation prefix of the chosen port
#
