Build
* C++ standard is std17
* Using this standard, all supported toolchains across our CI matrix will work.
* The code is not yet modified to use std17:
* If needed: ``-DCMAKE_CXX_STANDARD=14`` to lower the standard.
* The user's documentation is built by default.
* The doxygen documentation is built by default.
For developers:
* Set `-DUSE_CLANG_TIDY=ON` for clang tidy checks.
* Tidy checks are done on CI.
Documentation build
* The doxygen documentation is built by default
* The HTML documentation is built by default
* The translated languages (en, es, sv, zh_Hans) HTML documentation are built by
default
* `WITH-DOC` is not used anymore
User Documentation is not built when
* Sphinx is not found
* When all Sphinx formats are OFF
* To not build HTML default format: `-DBUILD_HTML=OFF`
* When all languages are OFF
* To build only English: `-DES=OFF -DSV=OFF -DZH_HANS=OFF`
* Documentation output location: [`build/doc/_build/](format)`
* For example: for HTML output is on `build/doc/_build/html` directory
Developers' Documentation is not built when
* Doxygen is not found
* To not build Doxygen documentation: `-DBUILD_DOXY=OFF`
