# - Having libmain in libraries should pull implicitly libexposed and libinternal in Libs.private
# - Having libexposed in libraries should remove it from Libs.private
# - We generated a pc file for libexposed so it should be in Requires instead of Libs
# - Having threads_dep in libraries should add '-pthread' in both Libs and Cflags
# - Having custom_dep in libraries and libraries_private should only add it in Libs
# - Having custom2_dep in libraries_private should not add its Cflags
# - Having pc_dep in libraries_private should add it in Requires.private
# - pc_dep_dup is the same library and same version, should be ignored
# - notfound_dep is not required so it shouldn't appear in the pc file.
