Local conan package dependency including multiple libs

Question

I'm new to conan and I'm trying to structure my project (let's call it BaseProject) using it. In particular I'm trying to add another local project as a dependency to it.

BaseProject has the following conanfile.txt:

[requires]
other_project/1.0

[generators]
cmake

other_project is a separate project being built using make, which generates three static libraries: libfoo1.a, libfoo2.a, libfoo3.a

So I created a conanfile.py under OtherProject to add that project as a local package. The conanfile.py is the following:

from conans import ConanFile, AutoToolsBuildEnvironment
from conans import tools


class OtherProjectConan(ConanFile):
    name = "other_project"
    version = "1.0"
    settings = "os", "compiler", "build_type", "arch"
    generators = "cmake"
    exports_sources = "Makefile", "src/*"

    def build(self):
        with tools.chdir("."):
            atools = AutoToolsBuildEnvironment(self)
            atools.make()

    def package(self):
        self.copy("*.h", dst="include", src="src")
        self.copy("*.lib", dst="lib", keep_path=False)
        self.copy("*.a", dst="lib", keep_path=False)

    def package_info(self):
        self.deps = {"libfoo1": [], "libfoo2": [], "libfoo3": []}
        # self.cpp_info.libs = ["libfoo1", "libfoo2", "libfoo3"]

src has three separates folder under it, each with its own makefile, which are all included from the base one.

After installing the package with conan, everything runs smoothly, and I can actually find libfoo1.a, libfoo2.a and libfoo3.a in the conan local cache.

Then I build BaseProject, which has the following CMakeLists.txt:

cmake_minimum_required(VERSION 3.9)
project(base_project VERSION 0.1 LANGUAGES CXX)

include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
conan_basic_setup()

...

add_executable(base_project main.cpp)

target_link_libraries(base_project PRIVATE ${CONAN_LIBS})
install(TARGETS base_project DESTINATION ${INSTALL_BIN_DIR})

But during the linking phase I get the following error:

/usr/bin/ld: cannot find -lother_project
collect2: error: ld returned 1 exit status

This probably means that conan is looking to find a libother_project.a, but instead I'd like it to search for the three other libraries.

I tried two different approaches in the package_info() (the commented out line), but the result did not change.

I'm sorry if this happens to be a trivial question, but I'm new to conan, and after some googling I could not find a solution to this.

Thanks in advance.
