-II. In your own environment (IDE)
----------------------------------
+ If you want to build FreeType 2 in another directory, you must set
+ two environment variables, `OJB_DIR' and `TOP'. The former gives
+ the directory where the object files and the library should be
+ created (this directory must exist), the latter the top directory of
+ the FreeType 2 source tree. Example:
+
+ OBJ_DIR=~/freetype2.compiled TOP=~/freetype2 \
+ make -f$TOP/Makefile setup ansi
+ OBJ_DIR=~/freetype2.compiled TOP=~/freetype2 \
+ make -f$TOP/Makefile
+
+ On Unix boxes, calling `configure' from the build directory is
+ sufficient; it will build a small Makefile which calls the
+ FreeType 2 Makefile with the necessary parameters.
+
+
+III. In your own environment (IDE)
+----------------------------------
You need to add the directories "freetype2/include" to your include
path when compiling the library.
