Error in fail: The following libraries were linked statically by different cc_shared_libraries but not exported:
cc_shared_library @@//src/path/to/lib:lib:
  "@@//src/path/to:include_root",
  "@@x//:libx_headers",
  "@@cpputils//:cpputils",
If you are sure that the previous libraries are exported by the cc_shared_libraries because:
  1. You have visibility declarations in the source code
  2. Or you are passing a visibility script to the linker to export symbols from them
then add those libraries to roots or exports_filter for each cc_shared_library.

cc_library(
    name = "cpputils",
    hdrs = glob(["include/cpputils/fmt/*.h", "include/cpputils/*.hxx"]),
    includes = ["include"],
