[poky] Cross compilation - Could not find lua libs

[Jean-Fabien Arnaud]

Hello
I would like to compile https://github.com/sbernard31/lualwm2m with a poky toolchain, but it can not find lua library and i do not know why.
Lua 5.1 is installed, and I have no problem to compile with the « default » gcc.

$:~/build_arm$ cmake -DCMAKE_C_COMPILER=/opt/poky/1.6.1/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc ../lualwm2m/
-- The C compiler identification is GNU 4.8.2
-- Check for working C compiler: /opt/poky/1.6.1/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc
-- Check for working C compiler: /opt/poky/1.6.1/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc -- works

I hope i am publishing on the good ML, if anybody can tell me what am I doing wrong ?

Thank you
