# - 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
|
|
|
