Debian stable build fails not finding lua.h

[nrnrnr]

I hope I have followed the build instructions correctly. I cannot get lwan to build; it is looking for a lua.h, but there must be an option -I/usr/include/lua5.1 missing somewhere. Cmake finds that Lua 5.1.3 is installed, but make cannot build.

Running on Debian stable (bullseye).

Attached is the full output from cmake and then make in a pristine build directory.

That seems like a bug in the Debian package: just looked here and the .pc file provided by liblua-5.1-0-dev has the following line: includedir=${prefix}/include, where prefix is defined to /usr. This would need to be something along the lines of includedir=${prefix}/include/lua5.1.

Please file a bug in Debian.

I'm not seeing an issue with pkg-config (which I use heavily):

nr@homedog ~/e/r/tfp23> pkg-config --cflags lua5.1
-I/usr/include/lua5.1

I attach one of the .pc files in the package. Please notice that although includedir is indeed set to ${prefix}/include, the CFLAGS are set as follows:

Cflags: -I${includedir}/${lib_name_include}

lua51.pc
