[CMake] Building shared library from collection?

[Hilton Medeiros]

Personally, I prefer a sole CMakeLists.txt for small/medium size
projects. You should not have problems linking your project, this
would be my approach:

list(APPEND LINK_MODULES PATHLIB/libA.a PATHLIB/libB.a PATHLIB/libC.a)
target_link_libraries(super_lib ${LINK_MODULES})

Note that you should use CMake defined paths in 'PATHLIB', e.g.,
${PROJECT_BINARY_DIR}/libA.a

I'm assuming they are static libraries since you said 'modules'.
Also, consider generating the html documentation from your cmake for use
as reference: 'cmake --help-html >cmake.html' on the command line.

Cheers,
Hilton
