# - Find Perl libraries

# and libraries are. It also determines what the name of the library is. This
# code sets the following variables:
#
# PERL_EXECUTABLE = full path to the perl binary
# PERL_INCLUDE_PATH = path to where perl.h can be found
# PERL_LIBRARY = path to where libperl.so* can be found
# PERL_CFLAGS = perl compiler options for compiling
# PERL_LFLAGS = perl compiler options for linking
if(PERL_FOUND)
# Already in cache, be silent
set(PERL_FIND_QUIETLY TRUE)
