# Finds the PCRE2 library, specify the starting search path in PCRE2_ROOT.

# Static vs. shared
|
||
|
|
# -----------------
|
||
|
|
# To make use of the static library instead of the shared one, one needs
|
||
|
|
# to set the variable PCRE2_USE_STATIC_LIBS to ON before calling find_package.
|
||
|
|
# Example:
|
||
|
|
# set(PCRE2_USE_STATIC_LIBS ON)
|
||
|
|
# find_package(PCRE2 CONFIG COMPONENTS 8BIT)
|
||
|
|
#
|
||
|
|
# This will define the following variables:
|
||
|
|
#
|
||
|
|
# PCRE2_FOUND - True if the system has the PCRE2 library.
|
||
|
|
# PCRE2_VERSION - The version of the PCRE2 library which was found.
|
||
|
|
#
|
||
|
|
# and the following imported targets:
|
||
|
|
#
|
||
|
|
# PCRE2::8BIT - The 8 bit PCRE2 library.
|
||
|
|
# PCRE2::16BIT - The 16 bit PCRE2 library.
|
||
|
|
# PCRE2::32BIT - The 32 bit PCRE2 library.
|
||
|
|
# PCRE2::POSIX - The POSIX PCRE2 library.
