# pcre2-config.cmake
# ----------------
#
# Finds the PCRE2 library, specify the starting search path in PCRE2_ROOT.
#
# Static vs. shared
# -----------------
# To force using the static library instead of the shared one, one needs
# to set the variable PCRE2_USE_STATIC_LIBS to ON before calling find_package.
# If the variable is not set, the static library will be used if only that has
# been built, otherwise the shared library will be used.
#
# The following components are supported: 8BIT, 16BIT, 32BIT and POSIX.
# They used to be required but not anymore; all available targets will
# be defined regardless of the requested components.
# Example:
#   set(PCRE2_USE_STATIC_LIBS ON)
#   find_package(PCRE2 CONFIG)
#
# 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.
