+# This file exports macros that emulate some functionality found in GNU libtool
+# on Unix systems. One such feature is convenience libraries. In this context,
+# convenience library is a static library that can be linked to shared library
+# On systems that force position-independent code, linking into shared library
+# normally requires compilation with a special flag (often -fPIC). To enable
+# linking static libraries to shared, we compile source files that come into
+# static library with the PIC flag (${CMAKE_SHARED_LIBRARY_C_FLAGS} in CMake)
+# Some systems, like Windows or OSX do not need special compilation (Windows
+# never uses PIC and OSX always uses it).
+#
+# The intention behind convenience libraries is simplify the build and to reduce
+# excessive recompiles.
+
+# Except for convenience libraries, this file provides macros to merge static
+# libraries (we need it for mysqlclient) and to create shared library out of
+# convenience libraries(again, for mysqlclient)
+
+# Following macros are exported
+# - ADD_CONVENIENCE_LIBRARY(target source1...sourceN)
+# This macro creates convenience library. The functionality is similar to
+# ADD_LIBRARY(target STATIC source1...sourceN), the difference is that resulting
+# library can always be linked to shared library
+#
+# - MERGE_LIBRARIES(target [STATIC|SHARED|MODULE] [linklib1 .... linklibN]
+# [EXPORTS exported_func1 .... exported_func_N]
+# [OUTPUT_NAME output_name]
+# This macro merges several static libraries into a single one or creates a shared
+# library from several convenience libraries
+
+# Important global flags
+# - WITH_PIC : If set, it is assumed that everything is compiled as position
+# independent code (that is CFLAGS/CMAKE_C_FLAGS contain -fPIC or equivalent)
+# If defined, ADD_CONVENIENCE_LIBRARY does not add PIC flag to compile flags
+#
+# - DISABLE_SHARED: If set, it is assumed that shared libraries are not produced
+# during the build. ADD_CONVENIENCE_LIBRARY does not add anything to compile flags
