+2. Installed revised CMake configuration files provided by Jan-Willem Blokland.
+This extends the CMake build system to build both static and shared libraries
+in one go, builds the static library with PIC, and exposes PCRE2 libraries
+using the CMake config files. JWB provided these notes:
+
+- Introduced CMake variable BUILD_STATIC_LIBS to build the static library.
+
+- Make a small modification to config-cmake.h.in by removing the PCRE2_STATIC
+ variable. Added PCRE2_STATIC variable to the static build using the
+ target_compile_definitions() function.
+
+- Extended the CMake config files.
+
+ - Introduced CMake variable PCRE2_USE_STATIC_LIBS to easily switch between
+ the static and shared libraries.
+
+ - Added the PCRE_STATIC variable to the target compile definitions for the
+ import of the static library.
+
+Building static and shared libraries using MSVC results in a name clash of
+the libraries. Both static and shared library builds create, for example, the
+file pcre2-8.lib. Therefore, I decided to change the static library names by
+adding "-static". For example, pcre2-8.lib has become pcre2-8-static.lib.
+[Comment by PH: this seems to be MSVC-specific. It doesn't happen on Linux.]
