# This macro displays the name and value of a CMake variable.
# The variable name is expanded with spaces to be (at least)
# <min_len> (currently 24) characters wide for better readability.
# VARNAME must be a string literal, e.g. WIN32 or "WIN32".
#
# Syntax:
# fl_debug_var(VARNAME)
#
# Example:
# fl_debug_var(WIN32)
# fl_debug_var("UNIX")
