Hi Francesco,

What OS are you working on?  And what value did you try using?  On
OSX, I have this in my CMakeCache.txt:

LUA_H_PATH:PATH=/usr/local/include

Again sorry ...
i'm on linux Ubuntu 12.04 32 bit.
Lua header files are in /usr/local/include or in
/usr/local/include/luajit-2.0.
i tried both in cmake GUI, adding a entry LUA_H_PATH, and in command line
cmake -D"LUA_H_PATH=/usr/local/include/".
But seems to remain empty (LUA_H_PATH="", so disabling BUILD_LUA_INTERFACE).

Maybe am i wronging something as usual? :)

Thanks,
ciao,
francesco.

ok, looking at CMakeLists.txt i have found this

# Relative install paths
set(EXECUTABLE_INSTALL_DIR "bin")
set(LUA_H_PATH "")

i changed the last line with the right path, i know this should be not the
way, but worked :)

Thanks,
ciao,
francesco.

The code change has broken things here for
/usr/local/include/luajit-2.0. I'm reverting it, minus the setting of
LUA_H_PATH to "".

Hello Andres,
i made this
cmake -D"LUA_H_PATH=/usr/local/include/" and cmake
-D"LUA_H_PATH=/usr/local/include/luajit-2.0"
but did not work. But Your command is different so maybe (well .. for sure
:)) i was wrong. I will try.

Thanks,
ciao,
francesco

Hello Michael,
in my system (Ubuntu 12.04) i have lua.h and lua.hpp either in
/usr/local/include that in /usr/local/include/luajit-2.0 so i guess on linux
should work, if you have both Lua that LuaJIT.

Thanks,
ciao,
francesco.

No, this worked just fine on OSX and and Linux for searching for
luajit and you've now broken it twice for me.  This has worked for a
long while.

When you make; make install luajit on Windows, does it not install
into /usr/local/include/luajit-2.0/lua.h?

I have not built the Lua stuff on Windows. I can take a look at it
shortly, but the changes you have reapplied are certainly not correct
as they remove dependency checks on the header (and break things on
OSX and Linux...)

I'm going to undo your commit again here and modify to use
PATH_SUFFIXES for sub directory search paths.  I will be pushing
commits and testing across platforms for the moment, please do not
make any commits while I'm in the middle of this.

I've modified the CMake files to use PATH_SUFFIXES, and also modified
them to search for lua51 if luajit or luajit-5.1 libraries are not
found.  This matches up with lua51.dll being generated on Windows with
LuaJit's default Makefile settings.

I built and installed LuaJit-2.0.3 with make install.  Afterwards, I
copied lua51.dll into /usr/local/lib.   With the changes, I can build
on OSX and Windows.

Michael: could you give this a try and let me know if the build is
working out there?
