| # FindPCRE2 | ||
| # -------- | ||
| # | ||
| # Find PCRE2 library | ||
| # | ||
| # Imported Targets | ||
| # ^^^^^^^^^^^^^^^^ | ||
| # | ||
| # This module defines :prop_tgt:`IMPORTED` target: | ||
| # | ||
| # ``PCRE2::PCRE2`` | ||
| # The pcre2 library, if found. | ||
| # | ||
| # Result Variables | ||
| # ^^^^^^^^^^^^^^^^ | ||
| # This module will set the following variables in your project: | ||
| # | ||
| # ``PCRE2_FOUND`` | ||
| # True if PCRE2 has been found. | ||
| # ``PCRE2_INCLUDE_DIRS`` | ||
| # Where to find pcre2.h | ||
| # ``PCRE2_LIBRARIES`` | ||
| # The libraries to link against to use PCRE2. | ||
| # ``PCRE2_VERSION`` | ||
| # The version of the PCRE2 found (e.g. 10.42) | ||
| # | ||
| # Obsolete variables | ||
| # ^^^^^^^^^^^^^^^^^^ | ||
| # | ||
| # The following variables may also be set, for backwards compatibility: | ||
| # | ||
| # ``PCRE2_PCRE2_LIBRARY`` | ||
| # where to find the PCRE2_PCRE2 library. | ||
| # ``PCRE2_INCLUDE_DIR`` | ||
| # where to find the pcre2.h header (same as PCRE2_INCLUDE_DIRS) | ||
| # | ||
