# The BLAS_LIB and LAPACK_LIB variables (among others) in cvxopt's
# setup.py are passed in as colon-delimited strings. So, for example,
# if your blas "l" flags are "-lblas -lcblas", then cvxopt wants
# "blas;cblas" for BLAS_LIB.
#
# The following function takes a flag type ("l", "L", or "I") as its
# first argument and a list of packages as its remaining arguments. It
# outputs a list of libraries, library paths, or include paths,
# respectively, for the given packages, retrieved using pkg-config and
# deduplicated, in the appropriate format.
