#

# As a preliminary, create a compilation directory and change into it, for

# example

#

#   mkdir ~/freetype2.compiled

#   cd ~/freetype2.compiled

#

# Now you can say

#

#   cmake <path-to-freetype2-src-dir>

#

# to create a Makefile that builds a static version of the library.

#

# For a dynamic library, use

#

#   cmake <path-to-freetype2-src-dir> -D BUILD_SHARED_LIBS:BOOL=true

#

# For a framework on OS X, use

#

#   cmake <path-to-freetype2-src-dir> -D BUILD_FRAMEWORK:BOOL=true -G Xcode

#

# instead.

#

# For an iOS static library, use

#

#   cmake -D IOS_PLATFORM=OS -G Xcode <path-to-freetype2-src-dir>

#

# or

#

#   cmake -D IOS_PLATFORM=SIMULATOR -G Xcode <path-to-freetype2-src-dir>

#

# Please refer to the cmake manual for further options, in particular, how

# to modify compilation and linking parameters.

#

# Some notes.

#

# . `cmake' creates configuration files in

#

#     <build-directory>/include/freetype/config

#

#   which should be further modified if necessary.

#

# . You can use `cmake' directly on a freshly cloned FreeType git

#   repository.

#

# . `CMakeLists.txt' is provided as-is since it is normally not used by the

#   developer team.

#

# . If you want to disable the automatic generation of the distribution

#   targets, add the `-D FREETYPE_NO_DIST=true' command line argument.

#

# . Set the `WITH_ZLIB', `WITH_BZip2', `WITH_PNG', and `WITH_HarfBuzz'

#   CMake variables to `ON' or `OFF' to force or skip using a dependency.

#   Leave a variable undefined (which is the default) to use the dependency

#   only if it is available.  Example:

#

#     cmake ... -DWITH_ZLIB=ON -DWITH_HarfBuzz=OFF ...

#

# . Installation of FreeType can be controlled with the CMake variables

#   `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL'

#   (this is compatible with the same CMake variables in zlib's CMake

#   support).
