# See LICENSE and NOTICE.md files in the root directory of this source tree.
#---------------------------------------------------------------------------------------
#-------------------------------------------------------------------------------------
# This is a CMake configuration file for building makefiles and installfiles for
# the Lomse library
#-------------------------------------------------------------------------------------
#
# To use it you need CMake which can be downloaded from http://www.cmake.org/
#
# Usage
# cmake [<options>] <source-tree>
#
# The default target (in Linux) is "Unix Makefiles". If you would like to generate
# a diferent makefile use option -G<desired-target>. For instance:
# cmake -G "Ninja" [...]
#
#
# Default configuration
# ~~~~~~~~~~~~~~~~~~~~~~~
# - Build type is 'Release'
#
# - The Bravura.otf music font *IS INCLUDED* in the package.
# See "Bravura music font required to render scores" section.
#
# Please note that default values can be changed directly in the CMake GUI or
# through the command line by prefixing the option's name with '-D':
# i.e.: cmake -DLOMSE_DEBUG=ON ....
#
#
#
# ---------------------------------------------------------------------------
# Build options
# ---------------------------------------------------------------------------
#
# LOMSE_BUILD_MONOLITHIC (Default: OFF) [In development. Not yet implemented]
# To avoid dependencies, instead of linking with the required libraries,
# these libraries will be combined into lomse library so that the binaries
# will not have dependencies on any of these libraries.
# cmake -DLOMSE_BUILD_MONOLITHIC=ON [...]
#
# LOMSE_BUILD_STATIC_LIB (Default: OFF for Unix, ON for Windows)
# Build the static library
#
# LOMSE_BUILD_SHARED_LIB (Default: ON for Unix, OFF for Windows)
# Build the shared library
#
# LOMSE_BUILD_TESTS (Default: ON)
# By default the unit tests runner program 'testlib' is also built.
# You can disable building the tests with this option:
# cmake -DLOMSE_BUILD_TESTS:BOOL=OFF [...]
# When the tests are not build, the dependency from 'UnitTest++' is
# automatically removed.
#
# LOMSE_RUN_TESTS (Default: ON)
# When unit test runner program 'testlib' is built (enabled by default and
# controlled by option LOMSE_BUILD_TESTS) the tests will be automatically run
# after building the library. You can disable running the tests with
# this option:
# cmake -DLOMSE_RUN_TESTS:BOOL=OFF [...]
# But LOMSE_RUN_TESTS is useless when LOMSE_BUILD_TESTS == OFF
#
# LOMSE_BUILD_EXAMPLE (Default: OFF)
# Build the tutorial_1 program that uses the library, to test it.
#
# LOMSE_USING_EMSCRIPTEN (Default: OFF)
# This option is used to inform this script that it is being run with
# Emscripten tools, for creating JavaScript bindings. When setting this,
# all other settings, such as LOMSE_BUILD_SHARED_LIB, LOMSE_BUILD_TESTS,
# LOMSE_ENABLE_COMPRESSION, etc. are ignored and this script will use
# instead pre-defined settings, as required for JavaScript bindings.
# cmake -DLOMSE_USING_EMSCRIPTEN=ON [...]
#
#
# Debug options (ON / OFF values):
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
# LOMSE_DEBUG (Default value: OFF)
# Force to create a debug build, with debug symbols. Default build type
# is 'Release'
#
# LOMSE_ENABLE_DEBUG_LOGS (Default value: OFF)
# Enable debug logs (performance loss). Doesn't require a debug build.
#
#
# Bravura music font required to render scores
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# LOMSE_INSTALL_BRAVURA_FONT (Default value: ON)
# By default, this font should not be included in Linux packages and the
# required font package must be set as an install dependency.
# As it is necessary to install it in Windows, and as in some Linux distros
# there is no package to install this font, this cmake scripts includes this
# font in the installer. To prevent this, you can use the option:
# cmake -DLOMSE_INSTALL_BRAVURA_FONT:BOOL=OFF [...]
#
# LOMSE_DOWNLOAD_BRAVURA_FONT (Default value: ON)
# When it is requested that Bravura font be included in the package, this
# cmake script will download the Bravura.otf font in case it is not found in
# the system. You can use the option:
# cmake -DLOMSE_DOWNLOAD_BRAVURA_FONT:BOOL=OFF [...]
# to force not to download it if not found in the system. But if the font is
# not found, it will not be installed in any case.
#
#
# Installation folders
# ~~~~~~~~~~~~~~~~~~~~~
#
# CMAKE_INSTALL_PREFIX
# The default installation prefix is "/usr/local" for Linux and
# "C:/Program Files (x86)" or "C:/Program Files" for Windows.
# You can change the install location by running cmake like this:
# cmake -DCMAKE_INSTALL_PREFIX=/new/install/prefix ...
#
# LOMSE_PKG_CONFIG_INSTALL (Default "/usr/lib/pkgconfig")
# As part of the Lomse instalation process, a pkg-config file, named
# liblomse.pc, is installed. The default location is "/usr/lib/pkgconfig".
# You can change this default location by using the option
# -DLOMSE_PKG_CONFIG_INSTALL=/new/pkgconfig/path. For instance:
# cmake -DLOMSE_PKG_CONFIG_INSTALL=/usr/lib/x86_64-linux-gnu/pkgconfig [...]
#
#
#
#
#
# ---------------------------------------------------------------------------
# Dependencies from external libraries
# ---------------------------------------------------------------------------
#
# lomse has these external dependencies:
#
# a) for all platforms:
# freetype https://gitlab.freedesktop.org/freetype/freetype
# libpng https://github.com/glennrp/libpng
# zlib https://github.com/madler/zlib
# UnitTest++ https://github.com/unittest-cpp/unittest-cpp
#
# b) additional, for Linux & macOS platforms (but not for Android):
# fontconfig https://gitlab.freedesktop.org/fontconfig/fontconfig
#
# It also uses (included as part of the surce tree):
# utfcpp
# agg
# pugixml
# MiniZip
#
#
# Options to reduce dependencies from other libraries (ON / OFF values):
# --------------------------------------------------------------------------
#
# LOMSE_ENABLE_PNG (Default value: ON)
# Build with support for PNG images. This requires the 'libpng' library.
# By setting this to OFF the dependency from 'libpng' is removed and
# Lomse will ignore any png image embedded in the documents, but will not
# fail if the document contains PNG images, it will just log an error
# message. Example for disabling:
# cmake -G "Unix Makefiles" -DLOMSE_ENABLE_PNG=OFF [...]
#
# LOMSE_ENABLE_COMPRESSION (Default value: ON)
# Build with support for compressed files. This requires the 'zlib' library.
# By setting this to OFF the dependency from 'zlib' is removed but Lomse will
# not be able to deal with compressed files, such as MusicXML files in
# compressed format, or with png images embedded in the documents.
# But Lomse will not fail in those cases, just will log error
# messages. Example for disabling:
# cmake -G "Unix Makefiles" -DLOMSE_ENABLE_COMPRESSION=OFF [...]
#
# **Important**: trying to disable compression without also disabling png
# has no effect because libpng depends on zlib. Therefore, when png is
# enabled (LOMSE_ENABLE_PNG=ON) then compression is automatically enabled.
#
# LOMSE_ENABLE_FONTCONFIG (Default value: ON)
# ** Only meaningfull in Linux systems **
# In Linux systems, build with support to look for fonts in system installed
# fonts. This requires the ‘fontconfig’ library.
# By setting this to OFF the dependency from 'fontconfig' is removed and
# Lomse will use only the fonts available in the path provided by the user
# application at Lomse initialization. Example for disabling:

# LOMSE_ENABLE_THREADS (Default value: ON)
# Build with support for threads. This requires the 'threads' library.
# Lomse uses threads for the ScorePlayer class, also used by ScorePlayerCtrl
