%description
BICPL is a programming library that provides higher-level functions 
on top of libminc, specifically for object manipulation and 
advanced volume operations used by the MNI autoreg tools.

%package devel
Summary:        Development files for %{name}
Requires:       %{name}%{?_isa} = %{version}-%{release}
Requires:       libminc-devel

%description devel
The %{name}-devel package contains libraries and header files for
developing applications that use %{name}.

%prep
# Tell setup the folder is named bicpl-<commit>
%setup -q -n bicpl-%{commit}

# ... rest of prep
# Create the directory for external macros
mkdir m4_external

# Extract the macros.
# Note: The folder inside the tarball will be 'mni-acmacros-master'
tar -xf %{SOURCE1} --strip-components=1 -C m4_external

%build
# 1. Regenerate configure script
mkdir -p m4
cp m4_external/*.m4 m4/
autoreconf -ifv -I m4

# 2. Patch configure to use Fedora library names
