Build and configuration
=======================
Build
-----
``xtl`` build supports the following options:
- ``BUILD_TESTS``: enables the ``xtest`` target (see below).
- ``DOWNLOAD_GTEST``: downloads ``gtest`` and builds it locally instead of using a binary installation.
- ``GTEST_SRC_DIR``: indicates where to find the ``gtest`` sources instead of downloading them.
- ``XTL_DISABLE_EXCEPTIONS``: indicates that tests should be run with exceptions disabled.
All these options are disabled by default. Enabling ``DOWNLOAD_GTEST`` or setting ``GTEST_SRC_DIR``
enables ``BUILD_TESTS``.
If the ``BUILD_TESTS`` option is enabled, the following target is available:
- xtest: builds an run the test suite.
For instance, building the test suite of ``xtl`` where the sources of ``gtest`` are located in e.g. ``/usr/share/gtest``:
.. code::
mkdir build
cd build
cmake -DGTEST_SRC_DIR=/usr/share/gtest ../
make xtest
