+# Add Precompiled Headers. If no target is given, this macro will fail with a FATAL_ERROR.
+# rationale: we need one PCH per static lib, since one global header would increase dependencies. To that end, we can either include them as
+# "projectdir/precompiled.h", or add "source/PCH/projectdir" to the include path and put the PCH there. The latter is better because many
+# projects contain several dirs and it's unclear where there the PCH should be stored. This way is also a bit easier to use in that
+# source files always include "precompiled.h".
+# Notes:
+# * Visual Assist manages to use the project include path and can correctly open these files from the IDE.
+# * precompiled.cpp (needed to "Create" the PCH) also goes in the abovementioned dir.
+# * using CMakes precompiled Header is not possible, as it does not allow for a custom name like used here.
