cmake added FetchContent support

Primary fixed paths CMAKE_SOURCE_DIR, PROJECT_SOURCE_DIR,
CMAKE_BINARY_DIR and similar.

An user can use the following code in the CMakeLists.txt file to
fetch and configure the TinyORM project from GitHub:

FetchContent_Declare(TinyORM
    GIT_REPOSITORY https://github.com/silverqx/TinyORM.git
    GIT_TAG        origin/main
)
# Here you can configure TinyORM CMake options
set(TOM_EXAMPLE ON)
FetchContent_MakeAvailable(TinyORM)
