| # FindJPEG |
| # -------- |
| # |
| # Find the JPEG library (libjpeg) |
| # |
| # Imported targets |
| # ^^^^^^^^^^^^^^^^ |
| # |
| # This module defines the following :prop_tgt:`IMPORTED` targets: |
| # |
| # ``JPEG::JPEG`` |
| # The JPEG library, if found. |
| # |
| # Result variables |
| # ^^^^^^^^^^^^^^^^ |
| # |
| # This module will set the following variables in your project: |
| # |
| # ``JPEG_FOUND`` |
| # If false, do not try to use JPEG. |
| # ``JPEG_INCLUDE_DIRS`` |
| # where to find jpeglib.h, etc. |
| # ``JPEG_LIBRARIES`` |
| # the libraries needed to use JPEG. |
| # ``JPEG_VERSION`` |
| # the version of the JPEG library found |
| # |
| # Cache variables |
| # ^^^^^^^^^^^^^^^ |
| # |
| # The following cache variables may also be set: |
| # |
| # ``JPEG_INCLUDE_DIRS`` |
| # where to find jpeglib.h, etc. |
| # ``JPEG_LIBRARY_RELEASE`` |
| # where to find the JPEG library (optimized). |
| # ``JPEG_LIBRARY_DEBUG`` |
| # where to find the JPEG library (debug). |
| # |
| # Obsolete variables |
| # ^^^^^^^^^^^^^^^^^^ |
| # |
| # ``JPEG_INCLUDE_DIR`` |
| # where to find jpeglib.h, etc. (same as JPEG_INCLUDE_DIRS) |
| # ``JPEG_LIBRARY`` |
| # where to find the JPEG library. |
