# depends_on("gmp")
# depends_on("mpfr")
# depends_on("pcre2")
# ARPACK: Requires BLAS and LAPACK; needs to use the same version as Julia.
# BLAS and LAPACK: Julia prefers 64-bit versions on 64-bit systems. OpenBLAS
# has an option for this; make it available as variant.
# FFTW: Something doesn't work when using a pre-installed FFTW library; need
# to investigate.
# GMP, MPFR: Something doesn't work when using a pre-installed FFTW library;
# need to investigate.
# LLVM: Julia works only with specific versions, and might require patches.
# Thus we let Julia install its own LLVM.
# Other possible dependencies:
# USE_SYSTEM_OPENLIBM=0
# USE_SYSTEM_OPENSPECFUN=0
# USE_SYSTEM_DSFMT=0
# USE_SYSTEM_SUITESPARSE=0
# USE_SYSTEM_UTF8PROC=0
# USE_SYSTEM_LIBGIT2=0

# Explicitly setting CC, CXX, or FC breaks building libuv, one of

# how Spack sets up compilers, Julia should still use Spack's compilers,
# even if we don't specify them explicitly.
