|
|
------------
|
|
|
|
Find the Bluelib library and header directories
|

|
|
Imported Targets
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module defines the following :prop_tgt:`IMPORTED` target:
|
|
|
|
``Bluelib::Bluelib``
|
|
The Bluelib library, if found
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module will set the following variables in your project:
|
|
|
|
``Bluelib_FOUND``
|
|
true if the Bluelib C headers and libraries were found
|
|
``Bluelib_INCLUDE_DIR``
|
|
directories containing the Bluelib C headers.
|
|
|
|
``Bluelib_LIBRARY``
|
|
the C library to link against
|
|
|
|
Hints
|
|
^^^^^
|
|
|
|
The user may set the environment variable ``Bluelib_PREFIX`` to the root
|
|
directory of a Bluelib library installation.
