Updating with adding external library functionality and generation of…

[faberc]

… libraries instead of executables.

Probably not the most elegant method, but this adds the functionality of passing the "-l" argument to generate the CMakeLists.txt for a library instead of an executable. Also adds support for "includeLibraries" key in cmwalk.json to include external libraries, for example:

{
"includeLibraries": ["m"]
}

generate the following in CMakeLists.txt:

# Add external explicit libraries. Such as 'm' for libm (math.h).
target_link_libraries(${PROJECT_NAME} PRIVATE m)

This includes the libm libraries (which includes the commonly used "math.h" library) which normally wouldn't be included by default.

Hello Chuck,

Please check cmwalk/TopLevel_CMakeLists_Library.txt.jinja2, there are duplicate code. For example, there are two snippets handling LINKER_SCRIPT.

Thanks for your contribution.
