I can't run a program that uses allegro5 with cmake - c++

Question

EDIT: If you want to look at the code, here it is:
https://github.com/WalterCapa/PercolationCpp/tree/master
I'm making a program that uses allegro5 library to generate an animation.
Because i want to avoid the installation of the library on every computer that uses the program, i tried to paste the headers and the .so files in my project dir. So the tree is like this:
root
include
allegro5 <- (Dir where the headers of allegro are)
Percolation.h
QuickUnion.h
lib
allegro5 <-(Dir where the .so files are)
Percolation.cpp
QuickUnion.cpp
PercolationVisualizer <- (Dir that has the main)
The problem is this. I installed allegro5 in my pc with LinuxMint 13. Everything is fine if I compile from Code::Blocks or if I do it from the terminal using -I to call the hedaers and -L to tell where the .so files are, and even using cmake works fine, but when i try to do it in another computer, even if it's windows like my laptop or a virtual machine with linuxmint, it generates this error:
make[2]: *** No rule to make target '/./lib/allegro5/liballegro.so/', needed by'
../bin/PercolationVisualizer'. Stop.
make[1]: *** [CMakeFiles/PercolationVisualizer.dir/all] Error 2
make: *** [all] Error 2
This is my CMakeLists.txt:
cmake_minimum_required(VERSION 2.8.7)
project(PercolationCpp)
set(PercolationCpp_VERSION_MAJOR 0)
set(PercolationCpp_VERSION_MINOR 1)
set(EXECUTABLE_OUTPUT_PATH ../bin/)
set(percolation_SRCS PercolationVisualizer/PercolationVisualizer.cpp lib/Percolation.cpp lib/QuickUnion.cpp)
#Executable
add_executable(PercolationVisualizer ${percolation_SRCS})
#include Allegro
include_directories(./include)
link_directories(./lib/allegro5)
#connect all the libraries
set(allegro5_LIBS /./lib/allegro5/liballegro.so /./lib/allegro5/liballegro_primitives.so)
target_link_libraries(PercolationVisualizer ${allegro5_LIBS})
Btw, when trying it on windows with MinGW i used cmake -G "MinGW Makefiles" .. and mingw32-make.
It found the compiler and and cmake worked, but when i tried de second one it gave me the same error. In my desktop i'm compiling using g++.

Answer 1

I think that your actual problem is the leading / in this line:
set(allegro5_LIBS /./lib/allegro5/liballegro.so /./lib/allegro5/liballegro_primitives.so)
A leading slash will tell cmake to look for an absolute path (like /usr/lib...) and not prefix it with a CMAKE_*_DIR. Try this
set(allegro5_LIBS ${CMAKE_SOURCE_DIR}/lib/allegro5/liballegro.so ${CMAKE_SOURCE_DIR}/lib/allegro5/liballegro_primitives.so)
However I strong discourage you to include pre-built libraries in your project. If you can, integrate a tar-ball or a git-submodule. If the project you include is a cmake project itself, a simple call to add_subdirectory will make the targets (libraries usually) available to your project and create a dependency. If the project is based on configure you can use the ExternalProject-extension.
