# 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).
