cet_make_library: EXPORT_NAME argument is overwritten by automatic naming logic

[greenc-FNAL]

When using cet_make_library, if a user explicitly provides an EXPORT_NAME argument, it appears to be ignored/overwritten if the LIBRARY_NAME (or calculated target name) matches the pattern ${NAMESPACE}_${SUFFIX}.

In CetMakeLibrary.cmake, the logic appears to be:

cet_regex_escape("${namespace}" e_namespace)
if(CML_TARGET_NAME MATCHES "^${e_namespace}_(.*)$")
  set(CML_EXPORT_NAME "${CMAKE_MATCH_1}")
else()
  unset(CML_EXPORT_NAME)
endif()

This block runs after argument parsing, effectively overwriting any EXPORT_NAME passed by the user.

Example:

cet_make_library(
  LIBRARY_NAME phlex_int
  EXPORT_NAME module
  ...
)

Expected Result:
Target phlex::module is created/exported.

Actual Result:
Target phlex::int is created/exported because phlex_int matches the namespace pattern, and the explicit EXPORT_NAME module is discarded.

Workaround:
The user must rename the library to match the desired export name (e.g., phlex_module) to force the correct export name via the automatic logic. cet_make_library should respect the explicit EXPORT_NAME if provided.
