[CMake] Allowing to manually add external libraries

name: Hotfix
about: Quick bugfix with very localized and low impact changes.

Description Closes #4 (closed)

Changelog

• Adding possibility to declare manually EXTERNAL_LIBRARIES_LIST and INCLUDES_LIST

Hot to use it

You just need to add EXTERNAL_LIBRARIES_TO_FIND_LIST, EXTERNAL_LIBRARIES_LIST and INCLUDES_LIST to your configure.sh as a string input separating the files/folders with semicolon (;).

For example (see two last lines):

#!/bin/sh

# Set variables
export FELISCE_SOURCE="${FELISCE_SOURCE:-"$( cd "$(dirname "$0")" ; pwd -P )"/..}"
export FELISCE_BUILD="${FELISCE_SOURCE}/build"

# Set basic configuration
export FELISCE_BUILD_TYPE=${FELISCE_BUILD_TYPE:-"Release"}

# Clean
clear
rm -rf "${FELISCE_BUILD}/${FELISCE_BUILD_TYPE}/cmake_install.cmake"
rm -rf "${FELISCE_BUILD}/${FELISCE_BUILD_TYPE}/CMakeCache.txt"
rm -rf "${FELISCE_BUILD}/${FELISCE_BUILD_TYPE}/CMakeFiles"

# Configure
