This extends the modules documentation to clarify their intended usage is for other find modules rather than in projects directly.

FindCygwin
|
|
----------
|
|
|
|
Finds Cygwin, a POSIX-compatible environment that runs natively on Microsoft
|
|
Windows.
|
|
|
|
.. note::
|
|
|
|
This module is primarily intended for use in other :ref:`Find Modules` to help
|
|
locate programs when using the ``find_*()`` commands, such as
|
|
:command:`find_program`. In most cases, direct use of those commands is
|
|
sufficient. Use this module only if a specific program is known to be
|
|
installed via Cygwin and is usable from Windows.
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module defines the following variables:
|
|
|
|
``CYGWIN_INSTALL_PATH``
|
|
The path to the Cygwin root installation directory.
|
|
|
|
Examples
|
|
^^^^^^^^
|
|
|
|
Finding the Cygwin installation and using its path in a custom find module:
|
|
|
|
.. code-block:: cmake
|
|
:caption: FindFoo.cmake
|
|
|
|
find_package(Cygwin)
|
|
find_program(Foo_EXECUTABLE NAMES foo PATHS ${CYGWIN_INSTALL_PATH}/bin)
|
|
|
|
include(FindPackageHandleStandardArgs)
|
|
find_package_handle_standard_args(Foo REQUIRED_VARS Foo_EXECUTABLE)
|
|
|
|
