Thanks Ray.
I guess it might be, because I'm trying to use the executable on a Linux Mint LMDE(Debian) and I had made it on a Linux Mint(Ubuntu).
Right now, I'm trying to install Raylib on Linux Mint LMDE, but it's a struggle.
I have read that the installation can be as simple as this:
1. git clone https://github.com/raysan5/raylib.git
2. cd raylib
3. cmake . gives lots of errors
4. make
I fairly new to Linux and uses CodeBlocks and C99.
