# Build the PCRE2 library from source
#
# This will add a 'pcre2' target to CMake which will generate the libpcre2-8.a
# static library and the pcre2.h header. If your target requires PCRE2 you
# need to add a dependeny on the 'pcre2' target by adding add_dependencies(<target> pcre2)
# to the CMakeLists.txt. You don't need to link against the pcre2 library
# because the static symbols will be in MaxScale.
