#  :copyright: (c) 2017 Alex Huszagh.

# Description
# ===========
#
#   Use:
#       Move to a custom directory, ideally out of source, and
#       type `cmake $LXW_SOURCE $FLAGS`, where `LXW_SOURCE` is the
#       path to the libxlsxwriter project, and `FLAGS` are custom
#       flags to pass to the compiler.
#
#   Example:
#       For example, in the project directory, to build libxlsxwriter
#       and the unittests in release mode, type:
#           mkdir build && cd build
#           cmake .. -DBUILD_TESTS=ON -DCMAKE_BUILD_TYPE=Release
#           cmake --build . --config Release
#           ctest -C Release -V
#           cmake --build . --config Release --target install
#
#       If using a Makefile generator, you may use the simpler
#           mkdir build && cd build
#           cmake .. -DBUILD_TESTS=ON -DCMAKE_BUILD_TYPE=Release
#           make
#           make test
#           make install
#
#   Flags:
#       ZLIB_ROOT
#           The ZLIB root directory can be specified either through
#           an environment variable (`export ZLIB_ROOT=/usr/include`)
#           or using a flag with CMake (`-DZLIB_ROOT:STRING=/usr/include`).
#           This sets the preferred search path for the ZLIB installation.
#
#       BUILD_TESTS
#           Build unittests (default off). To build the unittests,
#           pass `-DBUILD_TESTS=ON` during configuration.
#
#       BUILD_EXAMPLES
#           Build example files (default off). To build the examples,
#           pass `-DBUILD_EXAMPLES=ON` during configuration.
#
#       USE_STANDARD_TMPFILE
#           Use the standard tmpfile() function (default off). To enable
#           the standard tmpfile, pass `-DUSE_STANDARD_TMPFILE=ON`
#           during configuration. This may produce bugs while cross-
#           compiling or using MinGW/MSYS.
#
#       USE_DTOA_LIBRARY
#           Use the third party emyg_dtoa() library (default off). The
#           emyg_dtoa() library is used to avoid sprintf double issues with
#           different locale settings. To enable this library, pass
#           `-DUSE_DTOA_LIBRARY=ON` during configuration.
#
#       USE_NO_MD5
#           Compile without third party MD5 support. This will turn off the
#           functionality of avoiding duplicate image files in the output xlsx
#           file. To enable this option pass `-DUSE_NO_MD5=ON` during
#           configuration.
#
#       USE_OPENSSL_MD5 Compile with OpenSSL MD5 support. This will link
#           against libcrypto for MD5 support rather than using the local MD5
#           support. MD5 support is required to avoid duplicate image files in
#           the output xlsx file. To enable this option pass
#           `-DUSE_OPENSSL_MD5=ON` during configuration.
#
#       USE_STATIC_MSVC_RUNTIME
#           Use the static msvc runtime library when compiling with msvc (default off)
#           To enable, pass `-DUSE_STATIC_MSVC_RUNTIME` during configuration.
#
#   Toolchains:
#       On multiarch Linux systems, which can build and run multiple
#       binary targets on the same system, we include an `i686-toolchain`
#       file to enable building i686 (x86 32-bit) targets on x86_64 systems.
#       To use the i686 toolchain, pass the `-DCMAKE_TOOLCHAIN_FILE` option
#       during CMake configuration. For example, from the build directory,
#       you would use:
#           cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/i686-toolchain.cmake
#
#   CMake Options:
#       CMake sets debug and release builds with the `CMAKE_BUILD_TYPE`
#       option, which can be set as a flag during configuration.
#       To build in release mode, pass `-DCMAKE_BUILD_TYPE=Release`
#       during configuration.
#
#       CMake sets the creation of static and shared libraries with the
#       `BUILD_SHARED_LIBS` option, which can be set as a flag during
#       configuration. To build a static library, pass
#       `-DBUILD_SHARED_LIBS=OFF` during configuration.
#
#   Generators:
#       CMake also supports custom build generators, such as MakeFiles,
#       Ninja, Visual Studio, and XCode. For example, to generate
#       a Visual Studio solution, configure with:
#           cmake .. -G "Visual Studio 14 2015 Win64"
#
#       For more information on using generators, see:
#           https://cmake.org/cmake/help/v3.0/manual/cmake-generators.7.html
