Summary:        Development files for the co-installable Lua 5.5 runtime
Requires:       %{name}-libs%{?_isa} = %{version}-%{release}

%description devel
Headers in lua5.5, the liblua5.5 linker name, and pkgconfig(lua55) metadata
for embedding Lua 5.5 without using Fedora's generic Lua development files.

# Upstream only builds a static archive. Build PIC objects first, then use
# that private archive to construct a real shared library. The archive is
# only an intermediate and is never installed or included in an RPM.
# POSIX and dlopen are enabled explicitly. The optional readline facility
# is deliberately disabled, avoiding a hidden dlopen-only runtime dependency.
