add_compile_options
-------------------
Add options to the compilation of source files.
.. code-block:: cmake
add_compile_options(<option> ...)
Adds options to the :prop_dir:`COMPILE_OPTIONS` directory property.
These options are used when compiling targets from the current
directory and below.
Arguments
^^^^^^^^^
Arguments to ``add_compile_options`` may use "generator expressions" with
the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)`
manual for available expressions. See the :manual:`cmake-buildsystem(7)`
manual for more on defining buildsystem properties.
.. include:: OPTIONS_SHELL.txt
Example
^^^^^^^
Since different compilers support different options, a typical use of
this command is in a compiler-specific conditional clause:
.. code-block:: cmake
if (MSVC)
# warning level 4 and all warnings as errors
add_compile_options(/W4 /WX)
else()
# lots of warnings and all warnings as errors
add_compile_options(-Wall -Wextra -pedantic -Werror)
endif()
See Also
^^^^^^^^
This command can be used to add any options. However, for
adding preprocessor definitions and include directories it is recommended
to use the more specific commands :command:`add_compile_definitions`
and :command:`include_directories`.
The command :command:`target_compile_options` adds target-specific options.
The source file property :prop_sf:`COMPILE_OPTIONS` adds options to one
source file.
